Psalm 52:1 Why do you boast of evil, you mighty hero? Why do you boast all day long, you who are a disgrace in the eyes of God?
What do you boast about? What are the things which you want other people to know about you? Are they Godly or worldly?
God doesn’t want to hear all about your worldly gains and prowess because He has to watch you doing that all day long; things which are building yourself up instead of praising and glorifying God!
You may well be a worldly celebrity or hero, but that counts as nought compared to what you can do for God!
