Acts 12:25-13:3 A Ministry Of Deed, Word, Prayer, And Fasting.
Certainly part of the ministry, which Barnabas shared with Saul and John-Mark, was the delivery of the gift from the Antiochian church to the church in Judea (11:27-30). Barnabas was no doubt instrumental in convincing Saul (Paul), to take John-Mark with them as their assistant (Cf. 11:22; 12:12; 13:5, 13; 15:36-41). “Possibly the young man who fled the night of Jesus’ arrest (Mark 14:51, 52). Mark, the writer of the second Gospel (cf. 1 Pet. 5:13), accompanied Paul and Barnabas down to Antioch and went with them on the first missionary journey (13:4) as far as Perga in Pamphylia (13:13)” (NGSB p. 1733). However, there was much more to their “ministry” then simply the transfer of this gift. These men, along with others, were also “prophets and teachers” of the word (13:1 Cf. Rom. 16:21).
They proclaimed “the word of this salvation” (13:26), and “they ministered to the Lord and fasted” (13:2a). So they combined the ministry of deed with that of the word, and they did all through a ministry of prayer and fasting to the Lord. They knew whom it was that they depended on. It was during this ministry of fasting and prayer that “the Holy Spirit said, “Now separate to Me Barnabas and Saul for the work to which I have called them.” Then having fasted and prayed, and laid hands on them, they sent them away” (vv. 2b-3; Cf. 6:6; 14:23; Gal. 1:15; 2:9; Heb. 5:4). As Paul noted later in his letter to the Galatians, “when James, Cephas, and John, who seemed to be pillars, perceived the grace that had been given to me, they gave me and Barnabas the right hand of fellowship, that we should go to the Gentiles and they to the circumcised” (2:9).
