 You see, that's your heart. Now that leads to a life or death challenge from God's word. It's in 2 Corinthians 13, 5. Listen to these words. Examine yourselves to see whether you are in the faith. Test yourselves. Do you not realize that Christ Jesus is in you? Unless, of course, you failed the test. Do what God says. Test yourself. It's eternally important to ensure that you don't miss heaven by 18 inches. That's the distance from your head to your heart.
