The plan of God as it unfolds in the book of Acts and into the epistles is to have churches established and built-up. This is God’s agenda for this age. In one sense the church is His mission plan for this age. Churches are established and out of those churches other churches are established.
I have been pondering on this issue particularly as regards to the sending out of missionaries to other pasts of the world. The goal should always be for those sent out either to link with churches which are already in situ in the location where they go to, or if it is a completely spiritually barren area to establish new churches.
There is something wrong for people to be just loan rangers or loan groups operating independent of churches.
This also raises issues more close to home. To engage in evangelism is absolutely vital and we give thanks to the Lord for all mission agencies who are labouring for the Lord. But these should always be operating in connection with local churches.
The commission of our Lord is to go and make disciples. Disciples are formed in the context of a local church. A convert can be any where, but a disciple should always be in a church. Evangelism should always be about recruiting disciples.
