God is a forgiving God, that is his nature. Pray that people would turn in repentance and receive that free gift.
They refused to listen and failed to remember the miracles you performed among them. They became stiff-necked and in their rebellion appointed a leader in order to return to their slavery. But you are a forgiving God, gracious and compassionate, slow to anger and abounding in love. Therefore you did not desert them
If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
1 John 1:9
