One question I hear a lot is:
Q. When is it too late to “come back” to God?
A. Some teach that if someone experientially loses her faith, he or she can never come back. In essence, they teach that such persons have sealed their fate. That’s false.
Again, so it’s clear, I’m not talking about losing one’s salvation. I’m talking about losing one’s faith, which is a wonderful and invaluable gift from God. Someone can have lots of faith, and then lose it. Do they still have at least a “mustard seed” of faith? Yes. But it’s so small the person often is not consciously aware of it.
It is never too late to come back to God, no matter what you have gone through or what you have done. God wants to be back in relationship with you. Even if it's been a long time since you last spoke, you can come back to him today.
