The Lord is always right, always faithful, always loving, and never wrong. Book faith requires the Bible and familiarity with it. I know there is a heaven but there is only one place that gives you evidence, the Bible. It's the word of God! Man wouldn't write this because they don't want to point out that man is deceitful above all things and desperately wicked. Salvation is eternal, you cannot lose it. Your salvation gets you into Heaven, but it doesn't help you live the rest of your life. When you got saved, you didn't get smart. Through our lives, we can get smarter and smarter and it begins with the reading the bible. When you open the Bible, you're feeding the spiritual side of your body, it allows the spirit of God to direct you. There are two other faiths that brother Overton talks about.
