Holding on to past failures...recognize it for what it is...a trick of the enemy, a snare.
He comes to steal, kill, destroy. Don't let him!
Jesus comes to give life in all its fulness. John 10:10
And now from Psalm 119:97-104...
Oh, how I love Your law!
I think about it all day long.
Your commands make me wiser than my enemies,
for Your commands are my constant guide.
I have refused to walk on any path of evil,
(which incudes believing his lie re: your past failures)
that I may remain obedient to Your word.
Your commandments give me understanding;
no wonder I hate every false way of life.
