We are Kosie and Dorinda, evangelists and revivalists called by God to light the fires of revival, win the lost at any cost, and mobilise the Body of Christ for radical evangelism.

Founded
Garden Route
Home base, South Africa
A burningmandate.
Kosie and Dorinda van der Merwe are passionate revivalists and soul-winners, boldly carrying the fire of God across cities and nations. In 2017 they founded Rivers of Revival Ministries with a burning mandate: to see the harvest of souls brought into the Kingdom, to ignite the flames of revival, and to equip, empower and mobilise believers for end-time evangelism.
Based in the beautiful Garden Route of South Africa, they minister with boldness and compassion, travelling to cities and nations to host revival meetings, evangelism crusades and equipping events that stir hunger for God's presence and awaken the Body of Christ.
Through Rivers of Revival Ministries they are committed to seeing every believer set ablaze with the power of the Holy Spirit, trained to share the Gospel with boldness, and released into their God-given assignment. Their hearts burn for revival, reformation and global harvest, and they are seeing multitudes touched, healed, saved and transformed by the tangible presence of God.

Kosie van der Merwe · Founder, revivalist & evangelist
Kosie
Addicted at 12. Radically saved at 17. Called that same year.
Kosie van der Merwe is a bold and passionate revivalist and evangelist with a powerful testimony of transformation. After battling drug addiction from the age of 12, he encountered Jesus radically at 17, and everything changed. That same year he received a divine call to preach the Gospel to the nations with a demonstration of the Spirit and power.
Since then, Kosie has dedicated his life to seeing souls saved, lives transformed, and believers set ablaze with the fire of God. His ministry is marked by an evident anointing, bold preaching, and a tangible presence of God that brings healing, deliverance and breakthrough.
With a deep love for people and an unwavering passion for revival, Kosie has ministered across five nations, carrying a message of hope, restoration and the supernatural power of the Gospel. He is the founder of Rivers of Revival Ministries, through which he travels to cities and nations to spark revival, mobilise believers for evangelism, and usher in the end-time harvest.
Kosie lives on the Garden Route of South Africa with his wife Dorinda, where they are based when not on the road fulfilling the Great Commission.

Prayer first
Nothing moves before we have prayed.
The Gospel, plain
No gimmicks. Jesus, clearly preached.
Demonstration
Not with words only, but with a demonstration of power.
No door ignored
Big room or back room, we come the same.
People over platforms
One soul outweighs any stage.
Integrity in everything
In money, numbers and words.
Old truths.Fresh fire.
We hold historic, biblical Christianity with Pentecostal conviction: the full Gospel, preached with the expectation that God confirms His word.
The Bible is the inspired, trustworthy Word of God and the final authority for faith and life.
One God, eternally existing as Father, Son and Holy Spirit.
Salvation is by grace through faith in Jesus Christ alone, crucified for our sins and raised bodily from the dead.
The Holy Spirit empowers believers today, with gifts and demonstration, to live holy and witness boldly.
The Church is sent. Every believer carries the commission to make disciples of all nations.
Jesus Christ is coming again. The harvest is urgent because the time is short.
The road is long.The call is clear.
From the Garden Route to the nations, the pattern has not changed since 2017: God opens a door, and we go through it. Revival meetings, evangelism crusades, tents, streets and equipping events.
Their hearts burn for revival, reformation and global harvest. There is still one more soul.
