Scripture says that we walk by faith, not by sight. I've heard preachers and even read here that we need to "turn our lives over the Christ" - even said it myself. Got to admit that, though I've been a Christian for a long time, I haven't lived a consistent life and now, well, I'm just not sure what this really means. How do we walk by faith? Is this the "blank check" I've heard preachers refer to? If it is, how do you know if you've actually signed it? I try to live as I think God wants me to live... I'm just confused, I guess.
