In Acts, we see the role of the Church, the bride of Christ, is to give. The mission and witnessing came out of a place of worship, out of the life of a community of Jesus who were always together and praying.
While they were worshiping the Lord and fasting, the Holy Spirit said, “Set apart for me Barbaras and Saul for the work to which I have called them.” So after they had fasted and prayed, they placed their hands on them and sent them off.
Acts 13:2-3
