But Paul knew these new believers needed more attention if they were to become strong in their faith and multiply. From Acts 14 onward, Paul used an effective method by returning to these new believers and churches to “strengthen the souls of the disciples, encouraging them to continue in the faith” (14:22). This key principle remained throughout the remainder of his ministry (see Acts 15:32, 41; 16:5, 40; 18:23; 20:11).
We must make certain that this principle is a key building tool, not just for planting new churches, but for establishing existing churches so they become effective planters, building strong, self-governed, self-sustaining and self-propagating. If we follow Paul’s method, we will see the last people group reached with the gospel through God’s wisdom in the church.
