Regret

2 Timothy 4:7 - I have fought a good fight, I have finished my course, I have kept the faith:
1 Peter 5:8 - Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:
1 John 1:9 - If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
