I remember the Peter of the Gospels. The one who jumped off the boat to walk on the water, and then realized what he had done and started to sink. The one who one moment confessed Jesus as Messiah and moments later tells Jesus He shouldn't have to die. The one who swore he would not deny Jesus, then does so 3 times. So now we are into Galatians. After the resurrection, after the day of Pentecost. A new and improved Peter. Well, maybe not completely.
Galatians 2:11 "When Peter came to Antioch, I opposed him to his face, because he was clearly in the wrong."
Seems Peter had slipped. He was separating himself from the gentiles "because he was afraid of those who belonged to the circumcision group." (Vs 12) Others then followed suit.
But not Paul. He saw that they were "not acting in line with the truth of the gospel." (Vs. 13, and I love that line).
Peter should have known everything Paul did. Yet he slipped. He was still human. I take comfort in that. Mostly because I find myself more of a Peter than a Paul. I have to believe that there is a place in heaven for Peter. In spite of his flaws and failures, he is within the grace of Christ. Duh! If we didn't have flaws and failures, there wouldn't be a need for grace. But sometimes I feel like I push the limits of that grace. Sometimes I don't act in line with the truth of the gospel. And for those times, I need his grace. I need more of Him. And that is a good thing.
