If you don't mind, could you explain how you feel that you have lost him?
For now, I'll tell you that there is nothing you can ever do that will separate you from the love of God... and I mean nothing. And there is nothing you can ever do to cause him to ever leave your, or forsake you. God is an awesome and faithful God, and no matter how bad we mess things up, here is always right there to pick us back and up. And he doesn't do with a look of disappointment on his face, but rather, he does it with a warm and loving smile. I promise you that he is still with you, and all you have to do is reach out and he'll be more than willing to lift you up.
