"Guilt is banished through love and truth;
Fear-of-God deflects evil."
Proverbs 16:6 (The Message)
This reminds me of something someone very dear has had to tell me over and over again: "You cannot parent out of guilt. Use your guilt to convict you, seek forgiveness and then change, if change is needed. But, forgive yourself or it will only get worse."
I think this can be said for any relationship that we have with anyone. Let go of guilt. It gets us nowhere. This doesn't mean we shouldn't feel CONVICTION. Conviction motivates us to make it right and change. Guilt just keeps us stuck in the same behaviors. If we believe the Evil One, we will stay stuck in that guilt-thinking of "I can't change." or "I'm a horrible mother." or "I stink at marriage." But, if we believe the Truth and if we accept the Love that God has for us... well, then we KNOW we are set free from guilt! Just admit your wrongdoing and then ask God to help you. :-)
