Because he never repented. Sin isn't just murder or theft. Many sins happen when we don't even realize it. Looking at that beautiful woman in a lustful way, is a sin. Lying, no matter how small, is a sin. And as I recall, Bill Gates ripped a guy off to get to where he is now, so he's pretty guilty of sin. If we could work our way to heaven by being good,then Jesus wouldn't have had to die for us. The only way to bypass Jesus to get to heaven in to live a perfectly pure life. That's impossible. I once heard sin put a pretty good way. We as humans are standing at street level. Our moral code is about eye level. Lying is only about waist high in our moral code, while muderers and rapists and such would be down at foot level, real scum of the earth. But God doesn't see things from our level. He sees them from the level of the empire state buildings roof. So when he looks down, all those sins are still sins, and still fall unbelievably short of His standards. A true Christian will not commit murder. A true Christian has been changed by the blood of Christ.
