Why was Paul's meeting with Peter significant?
Paul’s meeting with Peter in Jerusalem was significant because, after about three years—thought to be in Arabia—Paul went up to Jerusalem for the first time to meet the Apostle Peter face to face. It was notable since they came from two totally different backgrounds, making the encounter quite a meeting; further details are not given in this context.
Les explains that after Paul’s three-year stint, which he thinks was down in Arabia, Paul finally goes up to Jerusalem for the first time and is going to meet the Apostle Peter face to face. Les imagines that was quite a meeting, because Paul and Peter were coming from two totally different backgrounds. He notes that the account will be carried further in the next program, so this context only introduces the meeting and its notable face-to-face nature.
