Want Mercy?
Pride (teaches): Conceal (cover) your sins or deny it
Humility (teaches): Confess your sins and admit it
Results of doing either one of the above (compared):
“He that covers his sins shall not prosper: but whosoever confesses and forsakes them shall have mercy.” (Proverbs 28:13)
In fact, when one “confesses” one’s own sins toward one another and “forsakes” them (repent, become ‘righteous’), “healing” may follow as well after ‘prayer’:
“Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous person is powerful and effective.” (James 5:16)
P/S:
He is the Merciful One.
