36Some time later Paul said to Barnabas, “Let us go back and visit the brothers in all the towns where we preached the word of the Lord and see how they are doing.” 37Barnabas wanted to take John, also called Mark, with them, 38but Paul did not think it wise to take him, because he had deserted them in Pamphylia and had not continued with them in the work. 39They had such a sharp disagreement that they parted company. Barnabas took Mark and sailed for Cyprus, 40but Paul chose Silas and left, commended by the brothers to the grace of the Lord. 41He went through Syria and Cilicia, strengthening the churches.
I love this passage because it shows that church leaders can disagree with something, but the mission can keep going. I think we need reminders from time to time that as long as we are preaching Jesus we are still on the same team.
