It may be unfair, but God is a just God. He saw what happened. He knows who hurt you, what you lost, what you’re struggling with. He’s not just going to bring you out; He’s going to bring you out better. God always causes you to triumph.
Your kids owe you nothing. You have a responsibility to them based on a decision you made that they had no say in. The very least you could do is love them. The very least.
