All of us are born with a tendency to follow Adam and Eve. "The woman you gave me." "The serpent deceived me." Humans have been embellishing and refining our ability to be master excuse makers ever since. Excuses keep us from trusting God, erode our human relationships and weaken our character. The default mode for the excuse maker is to shift blame instead of looking to God in repentance. Repentance brings hope. Excuses result in fear.
This how the Holy Spirit describes the difference.
"He who conceals his sins does not prosper, but whoever confesses and renounces them finds mercy" (Proverbs 28:13).
Concealing sins, excuse making, will not prosper before God. But repentance yields mercy and the blessing of God. Listen to yourself. Listen to your children. If you hear responses like these, excuses rule the day:
"I'm sorry, I didn't mean to be angry." "I guess I'm just tired." "He was mean to me." "If you were just a little nicer, it would be a lot easier." "Being inside because of the weather makes me cranky." "It wasn't my fault, I'm just not feeling well."
