The Bible teaches that there are levels of faith. You don’t have to have 100% perfect faith in the whole Bible in order to be saved from Hell right now. Have intellectual hang-ups about evolution or the Bible having contradictions? Look for the answers! Start with Norman Geisler’s When Critics Ask and When Skeptics Ask. Trust in Jesus now with all the trust and hope you can muster; and ask God to help you out. Jesus won’t let you down if you only try to put your trust in Him. That’s bare minimum faith and anyone can use that faith by simply making the choice.
