Peter is still like that fisherman he was before Jesus found him. Here is a man who thought a lot of himself, up until the time he heard the rooster crow. That was the lesson that he heard clearly. There was no mistaking that he was not the best thing since sliced bread.
Or a good peanut butter and jelly sandwich either.
Let me be clear – Peter was not about to mince words. His advice? "Humble yourself and He (God) will lift you up higher at the right time". In other words, don't hold out to get the recognition you (think) deserve. Back off, and God will see that you get your name in lights at just the right time.
That's a hard thing for us humans to do. We want people to khow what we have done, and how great we are. Maybe there is a lesson from "Mr. Hotstuff." At least, we know he got the point. Just in case you think you are "hot stuff", cool your jets. Let somebody else do the recognition thing. You don't need to toot your own horn.
