Church planting is an essential part of the great commission is church planting. To "occupy" till he comes ( Luke 19:13) is not simply to hide within our walls and sit, but an occupying force is to expand, to GO YE....Preaching, baptizing, reproducing churches and souls that reproduce.
The gates of hell are not attacking us, but we them... And we are instructed to go, the pastor (although not an evangelist) is instructed to do the work of an evangelist. We are to assist the evangelist in church planting and to multiply......there is a great work to do, and the sun is setting on the harvest.
Church planting to us is not an auxiliary ministry but is remains at the heart and soul of who we are and what we do.
