“When God completes all the goodness He has promised my master and sets you up as prince over Israel, my master will not have this dead weight in his heart, the guilt of an avenging murder. And when God has worked things for good for my master, remember me.” (1 Samuel 25:30-31)
How easily it would be to slip into the routine of "getting even".
Instead of turning it over to God.
This verse opened my eyes to why God commands that He is to seek revenge, not us.
