That assumes anyone would want you to walk away.
either way, God says he would never let go of us. So it could be said, Yes, he would never let us fall away in a sense, that he will never let HIS CHILDREN fall away.. Not sure how this would be a bad thing, Would you let your children fall? I would hope not.
How can I stop my children from doing wrong? I teach them and help them, but it's ultimately up to my children to make the right decisions
