The "Mission" of the local church is to save souls. Jesus' expressed mission was to seek and to save the lost" (Luke 19:10); and his body on earth today, the church (Eph. 1:22-23), is to do the same.
What does that mean in a local church setting?
It takes leaders who walk by faith and launch out aggressively to evangelize the whole world and our own communities. We must not allow the urgent to supersede the eternal. It takes members walking by faith to continue to emphasize the true "Mission" of the church and to genuinely, selflessly work to see it happen. Paul said in 1 Corinthians 3:6-9, "I have planted, Apollos watered; but God gave the increase..."
As leaders and members, we want to continue to sow the seed, plant the word of God, and let the Lord give the increase.
