Paul’s “press on” section of this passage is often used to emphasize the importance of not giving up as a Christian. Be careful not to lean too far into that idea, though. Paul isn’t in any way encouraging us to pat ourselves on the back. In fact, he’s pushing hard the other way. Everything is “garbage” compared to what Christ has done for us, and that includes Paul’s very impressive list of accolades. He said this specifically, which probably would have been a big deal for a prominent Jew at the time. Paul had literally laid it all aside because he found something more complete.
