Before Facebook.
Before YouTube.
Before livestreaming allowed a preacher to reach millions of people from a mobile phone, there was another medium connecting South Africans across cities, townships and rural communities.
Radio.
And for countless listeners, there was one voice that became almost impossible to forget.
It was powerful.
Unmistakably African.
It carried Scripture, humour, music, isiZulu proverbs and stories drawn from everyday life.
And somewhere in the middle of a sermon, that voice would suddenly ask:
“U-Amen usekhona?”
Is Amen still there?
Listeners knew exactly who was preaching.
Dr Sibongiseni David Gumbi.
Long before millions encountered him through radio, however, Gumbi had spent decades preaching in churches, townships, open-air meetings and communities living through some of the most difficult periods in South African history.
He became an Assemblies of God minister, evangelist, gospel musician, mentor to pastors, marriage counsellor and community leader.
Eventually, he became one of the most recognisable isiZulu preaching voices of his generation.
This is the story of Dr S.D. Gumbi — the preacher whose voice carried faith, conviction and hope to a nation.
From Rural Zululand
Sibongiseni David Gumbi was born on 10 January 1940 in Mahlabathini, near Ulundi, in KwaZulu-Natal, South Africa.
He grew up in rural Zululand in modest circumstances. His father worked as a migrant labourer while his mother cared for the family at home.
Gumbi's childhood unfolded during an era of severe racial and economic inequality. Apartheid would become formal government policy in 1948, shaping virtually every dimension of life for Black South Africans.
But another environment was also shaping the young Gumbi.
Zulu culture possessed a rich oral tradition.
Stories.
Proverbs.
Idioms.
Music.
Humour.
And the expressive power of isiZulu.
Years later, these would become some of Gumbi's greatest instruments as a preacher.
He developed an ability to take biblical principles and communicate them through language and illustrations ordinary people immediately understood.
His sermons did not sound like imported theology translated awkwardly into isiZulu.
They sounded African.
But before Gumbi could preach the Gospel to others, he first had to encounter it himself.
The 19-Year-Old Who Found Christ
In 1959, at approximately 19 years old, Gumbi's life changed when he encountered Pentecostal revival preaching.
The wider spiritual environment in which he emerged had been strongly influenced by African evangelistic movements, including the Back to the Bible movement associated with legendary South African evangelist Nicholas Bhengu.
Gumbi responded to the Gospel and committed his life to Jesus Christ.
Soon, an ability that would define his future began to emerge.
He could preach.
The young convert became involved in evangelism.
Street corners became pulpits.
Open spaces became places of ministry.
Bus stops became evangelistic opportunities.
Door-to-door visitation became missionary work.
There was no national radio audience.
No celebrity.
No enormous platform.
There was simply a young Christian convinced that people needed to hear the Gospel of Jesus Christ.
Following in the Footsteps of African Pentecostal Pioneers
One of the important influences on the environment in which Gumbi developed was Nicholas Bhengu.
Bhengu had become one of the great pioneers of African Pentecostal evangelism.
His campaigns demonstrated something important to a generation of African ministers: African preachers did not have to imitate Western missionaries to communicate Christianity effectively.
They could preach in African languages.
They could use African forms of communication.
They could raise African leaders.
They could build churches rooted in African communities.
And they could carry the Gospel with confidence.
Gumbi emerged within this world.
Through the Assemblies of God, he developed as an evangelist and pastor, received ministerial training and eventually became an ordained minister.
Yet Gumbi never became disconnected from ordinary African life.
The Bible was his theological foundation.
The people became his communication classroom.
Dr S.D. Gumbi and the Assemblies of God
Dr Gumbi spent more than six decades associated with the Assemblies of God in South Africa.
An important historical distinction should be made.
Gumbi was not the founder of the worldwide Assemblies of God, nor was he the original founder of the denomination in South Africa. The movement existed before his ministry.
He nevertheless became one of the significant Black Pentecostal ministers and senior leaders associated with the Assemblies of God and its Back to the Bible tradition in South Africa.
He preached.
He pastored.
He evangelised.
He trained younger ministers.
And over time, he became regarded as a father within the movement.
One particular South African community would become inseparable from his story:
Standerton.
The Preacher of Standerton
During the 1970s, Gumbi established his ministry base in Standerton, Mpumalanga, particularly in Sakhile Township.
The local Assemblies of God congregation became the centre of decades of ministry.
But Gumbi's understanding of pastoral ministry extended far beyond preaching on Sundays.
People came to him with marriage problems.
Family difficulties.
Community disputes.
Spiritual questions.
Grief.
And eventually, political conflict.
Standerton became more than the place where he pastored.
It became the place where his ministry would be tested.
South Africa was moving toward an increasingly turbulent period.
Preaching in a Country on Fire
By the 1980s, Black townships across South Africa were experiencing enormous political unrest.
Resistance to apartheid was intensifying.
Police repression increased.
Young people entered political struggle.
Communities became divided.
Funerals frequently became political gatherings.
Sakhile was not untouched.
Political unrest affected the Standerton community, particularly during the upheavals of 1984.
Gumbi found himself ministering among people dealing with death, anger, fear and political division.
He conducted funerals during periods of unrest and repeatedly preached against vengeance, calling communities toward peace and reconciliation.
This was Christianity being tested outside the safety of a church building.
There were grieving families.
Angry young people.
Fearful parents.
Communities demanding freedom.
And an apartheid state attempting to maintain control.
Gumbi's role as pastor placed him in the middle of that pain.
His message did not require people to pretend injustice did not exist. But he warned against allowing hatred and vengeance to destroy communities from within.
As South Africa moved through the violent final years of apartheid and eventually toward democracy, Gumbi became known not merely as a preacher but also as a community voice.
At the same time, another dimension of his ministry was flourishing.
Music.
When the Preacher Started Singing
Music was not merely decoration in S.D. Gumbi's ministry.
It became another vehicle for the Gospel.
In 1984, he established the S.O.S Choir — Save Our Souls Choir — in Standerton.
Young people became involved, and gospel music became another instrument of evangelism.
Among the music associated with Gumbi and the choir was “Hamba Mzalwane.”
His music carried many of the same qualities as his preaching:
Faith.
Encouragement.
Warning.
Perseverance.
And unmistakably African expression.
Gumbi could be preaching one moment and suddenly begin singing.
Then, almost as quickly, he would return to his sermon.
The boundary between preaching and music disappeared.
The preacher was singing.
And the singer was preaching.
The S.D. Gumbi Preaching Style
To understand Dr S.D. Gumbi's influence, one must understand how he communicated.
He preached in rich isiZulu.
Not merely English theology translated into Zulu.
His preaching drew deeply from African forms of communication.
He used izaga — traditional proverbs.
Metaphors.
Stories.
Humour.
Everyday situations.
He could make a congregation laugh and then, moments later, confront listeners with an uncomfortable spiritual truth.
His sermons addressed holiness, marriage, honesty, respect, death, eternity, heaven, hell, family responsibility, hard work and personal salvation.
Gumbi believed the Gospel did not need to be softened merely to make people comfortable.
An expression associated with that conviction captured his approach:
“Ivangeli alidingi ushukela.”
The Gospel doesn't need sugar.
But another expression would become even more closely associated with his name.
“U-Amen Usekhona?”
While preaching, Gumbi had a distinctive way of checking whether his congregation was still following him.
He would suddenly ask:
“U-Amen usekhona?”
Literally:
“Is Amen still there?”
It was another way of asking:
Are you still with me?
Are you listening?
Do you still agree?
The congregation would respond:
Amen!
It reflected the call-and-response tradition deeply embedded in African communal communication.
Then radio transformed it.
Gumbi was no longer asking only the people sitting inside a church:
“U-Amen usekhona?”
He was asking people sitting in kitchens.
Taxi drivers.
Security guards.
Families.
Workers on Sunday shifts.
Young people.
Grandmothers.
People in townships.
People in rural communities.
People hundreds of kilometres away.
Radio turned a local preacher into a national voice.
The Voice of Ukhozi FM
One of the greatest platforms of Gumbi's ministry came through Ukhozi FM, one of South Africa's largest radio stations.
His preaching became closely associated with the programme “Unkulunkulu Nomuntu Omusha.”
Radio suited Gumbi extraordinarily well.
There were no stage lights.
No enormous screens.
No visual effects.
The preacher had one primary instrument:
His voice.
And his voice was enough.
His command of isiZulu made biblical ideas accessible.
His humour held people's attention.
His stories created pictures in the imagination.
His music carried emotion.
And his preaching challenged listeners spiritually.
People who might never have attended an Assemblies of God congregation could encounter S.D. Gumbi through radio.
His congregation had expanded far beyond the walls of a church in Standerton.
And that unforgettable question travelled through the airwaves:
“U-Amen usekhona?”
A Father to Preachers
But Gumbi's legacy cannot be measured only by the number of people who heard his voice.
One of the most important questions in understanding any Christian leader's legacy is:
Who did they raise?
Gumbi became a mentor and spiritual father to younger ministers.
Among leaders who have publicly acknowledged his influence are Bishop N.D. Nhlapo of God Never Fails Ministries and Bishop T.E. Twala.
His approach to mentorship was practical.
Young ministers travelled with him.
They watched him preach.
They observed how he handled funerals.
They learned pastoral care.
They saw him interact with communities.
They experienced ministry beyond the classroom.
For Gumbi, ministry was something that had to be lived before it could be taught.
Eventually, those younger ministers developed ministries of their own.
His influence therefore continued through voices other than his own.
The Family Behind the Preacher
Behind the nationally recognised preacher was also a husband and father.
Gumbi was married to Evelyn Mangubeni Gumbi, who shared decades of life and ministry with him.
Their family included their children Nomsa, Sibusiso and Sibongile.
The public knew the preacher behind the microphone.
His family knew the man when the microphone was switched off.
The husband.
The father.
The man who travelled, counselled people, preached at funerals, mentored ministers and eventually returned home.
His family would also walk alongside him during one of the most difficult seasons of his life.
When the Body Became Weak
As Gumbi grew older, his health deteriorated.
Serious medical complications eventually resulted in the amputation of one of his legs.
The preacher who had once moved energetically across platforms now had to use a wheelchair.
For a man whose life involved travelling, preaching, singing and public ministry, the change was profound.
But losing mobility did not mean losing his voice.
Gumbi continued preaching.
The wheelchair became part of the platform.
His body had weakened.
His conviction had not.
There was something especially powerful about an elderly preacher who had personally experienced physical suffering continuing to encourage others to hold onto their faith.
By then, his ministry carried the authority of longevity.
He had preached under apartheid.
He had ministered during political violence.
He had witnessed Nelson Mandela's release.
He had watched South Africa become a democracy.
He had witnessed technology transform Christian communication.
And he had seen generations of younger preachers emerge.
Now he spoke as an elder.
His Message to the Next Generation
Gumbi represented an older Pentecostal tradition in which ministry was strongly associated with sacrifice, holiness, evangelism and service.
As Christian ministry changed around him, he continued emphasising foundational principles.
The Gospel was not primarily a pathway toward celebrity.
The preacher was a servant.
Character mattered.
Marriage mattered.
Integrity mattered.
Holiness mattered.
People mattered.
And the Gospel mattered more than the personality preaching it.
The man who had spent decades mentoring others increasingly spoke as a father concerned about what would happen when his generation was gone.
That day eventually came.
The Death of Dr S.D. Gumbi
On 14 July 2025, Dr Sibongiseni David Gumbi passed away at the age of 85.
News of his passing travelled across South Africa's Christian community.
Pastors paid tribute.
Musicians remembered him.
Radio personalities remembered his unmistakable voice.
Community and political leaders remembered his contribution to reconciliation and social cohesion.
Spiritual sons remembered their father.
And ordinary listeners remembered Sundays when a preacher they may never have met personally entered their homes through radio.
His funeral was held at Sakhile Community Stadium in Standerton.
It was a fitting location.
The community in which he had spent decades serving now gathered to say goodbye.
But the greatest memorial to a preacher is not necessarily what is said at his funeral.
It is what remains after the funeral is over.
The Legacy of Dr S.D. Gumbi
His sermons remain.
His music remains.
His spiritual sons remain.
The churches remain.
The people he counselled remain.
The ministers he mentored continue preaching.
Recordings allow generations who never sat under his ministry to hear his voice.
And somewhere, someone who grew up listening to Ukhozi FM can still remember exactly how he sounded when he asked:
“U-Amen usekhona?”
That simple expression became bigger than a preaching technique.
It represented Gumbi's relationship with his audience.
He did not simply preach at people.
He brought them into the sermon.
Are you still there?
Are you following?
Do you still believe?
Is Amen still there?
A Voice That Still Echoes
Dr S.D. Gumbi's story is not primarily the story of the biggest church building, the largest television network or Christian celebrity.
It is the story of a voice.
A voice formed in rural KwaZulu-Natal.
A voice shaped within African Pentecostal Christianity.
A voice refined through decades of preaching.
A voice that comforted grieving families during political violence.
A voice that could suddenly become a song.
A voice that could make people laugh.
A voice that could rebuke.
A voice that could encourage.
A voice that entered homes across South Africa through radio.
And a voice that helped raise other voices.
From Mahlabathini to Standerton.
From open-air evangelism to the Assemblies of God.
From the S.O.S Choir to gospel recordings.
From township pulpits to Ukhozi FM.
From political turmoil to reconciliation.
From standing behind the pulpit to preaching from a wheelchair.
Sibongiseni David Gumbi continued carrying the same message:
Jesus Christ saves.
Live right.
Love people.
Serve God.
Keep the Gospel uncompromised.
The microphone has fallen silent.
But the echo remains.
And perhaps there is only one appropriate way to end his story.
“U-AMEN USEKHONA?”
And from the churches, homes, ministers and lives touched by his ministry, the answer continues:
AMEN!
Dr Sibongiseni David Gumbi.
Preacher.
Evangelist.
Gospel musician.
Mentor.
Father.
A voice of hope to a nation.
A General of Impact.
