We are to be witnesses (not to be confused with witnessing). That means we must have seen and experienced the power of God. In Acts 8:1-8 churches were planted because the believers scattered because of persecution. The believers were witnesses wherever they went. Mark 16 notes that signs would follow the believers, not the apostolic. You have to go out to the harvest field. “You don’t kill the enemy at the headquarters.” The second way churches are planted is by believers being sent out. The Church will grow if each believer reproduces himself or herself. We need to walk in the fear of the Lord and in the comfort of the Holy Spirit.
