Note 1 at Ac 11:25: Barnabas befriended Saul when he was rejected by the Jerusalem church (Ac 9:26-27). This was many years later, and again, Barnabas was used by God as an instrument in Saul's life to bring him into public ministry. Only the Lord knows what the outcome might have been if Barnabas had not been present to encourage the Apostle Paul. God always uses men and women to accomplish His will. Although people may not have visible worldwide ministries, one of the few people that they alone can touch could become a minister who will shake nations for Christ.
