Only the actual goodness in your heart will enable you to stop being an atheist. If not you will not go to heaven, and the alternative is too horrible to contemplate. So if the joy of Heaven doesn't motivate you, then the eternal agony of the alternative had better. Those are the only two options, and Jesus alone holds the keys to the better one.Jackson,
Athiests do good deeds everyday. They just don't need to do it while drawing attention to their belief that god doesn't exist.
Maybe if Christians and other religos could separate their good works from their religion, we'd all know that it's out of the goodness of their hearts - not just to get into heaven.
Oh, and what constitutes Good, is God's call, not yours. You don't get to make up the rules, that was done by someone a whole lot smarter than any of us, a long, long time ago.
I will pray you overcome your lack of knowledge.
