If you feel like god won't let you go. You are probably right and that's reason enough to rejoice. If i told you how lonely and alone i have felt, i'm sure i could cause a tear to flow, but, psssst, i'll tell ya a secret. When i feel i am at the end of my rope, i can't see an end in sight, i feel miserable and sad to the core, alone, I throw on my favorite christian music and sing loudly. I praise him in the midst of my calamity! This is called the sacrifice of praise. When i feel like praising him the least is when i sing the loudest. And it works.
Confidence and faith and trust in god comes from battles won, not lost. Win the battles you will get the prize.
