 So if you were born, you're in the book of life. If you're even conceived, you're in the book of life. But if you've rejected the free gift of eternal life, you are blotted out of the book of life and you will be cast into the lake of fire. Well, that's cruel. God shouldn't do that. Listen, hell has to exist. Why? Because God is righteous. Since he is righteous, he has to judge sin.
