I used to say that I believed in God . . . but not the God of the Bible. Yes, I'd been in the "church" all my life, but hadn't ever read the Old Testament (not even in its scrambled form). It wasn't until I felt the Raw, Almighty Power of God (that nearly killed me) that woke me up. Once I realized that I breathe air because he simply allows it to happen, that's when I decided that I had better take my low-level form of belief and get myself straight.
After feeling the Love and Peace of God so Powerfully, and again, it was so Powerful being in the Lord's presence that it nearly killed me, I realized that I had better make the understanding of the Bible my number-one life's priority. I recommend that all people do the same thing. There is nothing more important than our figuring out the core message of the Bible . . . the ENTIRE Bible.
