If you find yourself saying, "I'm a bad mom," or even thinking it, those words are not from God. He doesn't label us & send us off to pasture; He loves us where we are & helps us grow from there. He is a loving Daddy who wants us to serve Him in our work & take pleasure in it!
Would you want your child to build a tower then declare, "I'm a terrible builder!"? It would break your heart. And as a parent, it wounds our Creator's heart as well to hear us condemn our efforts! God wants our words to speak life - even about ourselves.
