Proverbs 28:13 He who covers his sins will not prosper, but whoever confesses and forsakes them will have mercy.
Whilst we may wish to cover the sins of someone else, covering our own sins is wrong. Why so? Because covering someone else’s sins is showing them mercy, whilst covering your own is deceit.
Christ alone has the power to cover other people’s sins once and for all whereas we can forgive people of their sins toward us, but not toward God.
When we do open up our lives and confess our sins before God, He is able to forgive them and will forgive them. What an awesome God!
