"Go ye into all the world, and preach the gospel to every creature." Mark 16:15 (KJV)
The church is called to proclaim good news, heal the sick, deliver the oppressed, and set the captive free (Luke 4:18).  We have the answer to the World's problems and we must share Him. The purpose of the baptism of the Holy Spirit is the power to witness (Acts 1:8). All that we do in worship, prayer, fellowship and teaching is preparation for evangelism. God gave Jesus because He loved the world. His love has not changed; we are to go to the unsaved with this message of God's love.
