Some from Philippians I have made a “creed” of my life is found in 3:12-13. I have bad days, and sometimes those days are hard. Nevertheless, I refuse to have those days defeat me (cf. Hebrews 12:1-2). My bad day does not need to affect you adversely. It is tough enough when I experience it, why should I make you experience it?
What happened yesterday is history and the liklihood of me remembering it is not very good. Of course, there is a down side to this; as I have trained myself to leave the past in the past, especially the bad, sometimes the good stays there as well. When I need (or want) to recall, it fails me.
Just the same, a creed of my life is in 3:12-13
