By Prayer
"By prayer we are disciples and we make disciples who love and worship Jesus." — SIM Core Value
The Foundation
By Prayer — it's not just a tagline for SIM. It is the conviction on which our entire mission rests. "By Prayer" and in faith we depend on God for the provision of all our needs.
Prayer is how we praise God, seek his direction, request resources, and call upon the Holy Spirit to empower our ministries. It is the lifeblood of everything we do in South Africa and around the world.
When you pray for SIM South Africa, you are not a bystander to mission — you are a partner in it. Your intercession sustains missionaries, opens doors, and transforms communities.

For an awakening among South African churches that do not have a history of sending mission workers — that they will have effective service in cross-cultural missions.
For workers to take the gospel to the least reached, including children, youth, young adults, and Muslims, and to engage in effective ministry amongst them.
For the churches of South Africa to seek reconciliation and desire multi-cultural congregations that reflect the diversity of Christ's body.
For teachers to come alongside churches and schools to train up leaders to have a deeper understanding of the Scriptures, equipping the next generation of disciples.
For a deeper understanding of God's word and a spirit of oneness amongst staff, volunteers, and missionaries serving together across all of SIM's South African offices.
For SIM's work among Muslim communities in Cape Town and Johannesburg — that believers would have wisdom, courage, and love to share the gospel faithfully.
