Philippians 4:8 (King James Version)
8Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.
Another thing I have been told goes something like this..."You can't dwell on past mistakes and you can't dwell on current mistakes." I know this. Thinking of that I remembered part of another verse..."this one thing I do." Google is great to help you find the complete verse...
Philippians 3:13-14 (New Living Translation)13 No, dear brothers and sisters, I have not achieved it, but I focus on this one thing: Forgetting the past and looking forward to what lies ahead, 14 I press on to reach the end of the race and receive the heavenly prize for which God, through Christ Jesus, is calling us.
Because of all of this I can see my deep need for HIM! Put the past behind and leave the devil in the dust! Turn my eyes upon Jesus and think of Him only!
