Mark expands on how he'd have had Barnabas as a witness on Paul’s behalf. Barnabas knew first-hand that Synagogues were a place of learning, usually located near a body of water. Barnabas could share how Sabbath services functioned with Paul giving lectures proclaiming the good news to the Jews and those who feared God. Listen to how Mark would have Barnabas share the good and bad situations as noted in Acts 14, and how God equipped them to remain on mission, just as He does today in our lives.
