Even when we are too weak to have any faith left, he remains faithful to us and will help us, for he cannot disown us who are part of himself, and he will always carry out his promises to us (2 Tim 2:13, TLB).
Even if people have given up on you, rest assured that God hasn't! He sent His Son Jesus Christ to die on the cross for your sins and this God of grace will never give up on you. His arms are open wide to receive you, freely forgive you and restore to you!
