The centrality of the Church

We work hand-in-hand with evangelical churches, to send, support and receive gospel workers equipped to make disciples of Jesus, where people live and die without hearing the good news of Jesus.

More than 300 churches from the UK send workers overseas with us, and a growing number are now also receiving mission workers from overseas to help them reach out to their local communities.

If you are a church looking to send or receive mission workers, or you’d like access to training or resources, please do get in contact.
