This message examines how Paul recognised that he was a work in progress. He recognised the difference that Christ had already made in his life, but had set his mind on pressing towards perfection, because of the security that he had in Christ.

Philippians 3:12
English Standard Version
Straining Toward the Goal
12 Not that I have already obtained this or am already perfect, but I press on to make it my own, because Christ Jesus has made me his own.
