12 Not that I have already obtained, or am already made perfect. But I press on, that I may obtain that for which Christ Jesus also obtained.13 Brothers, I could not yet have obtained it. But one thing I do, I forget the things that are behind, and stretch forward to the things that are ahead.14 I press on toward the goal to the prize of the high calling of God in Christ Jesus.15 Let those of us who are mature have this attitude. If you have a different attitude God will show you how to think.
