I'm curious to know what pleasures, feelings, and activities you give up to live a "life of good." ie. being Christian.
When I converted from atheism to Christianity I did not give up any pleasures. I gave up certain things that might superficially seem like pleasures, but which in truth cause nothing but pain and grief. Pornography comes to mind; I have been vastly happier as a result of giving that up. Others I know have given up drugs, hard drinking, easy sex, gambling, and so forth, and all are much happier as a result of that.
I just dont understand why a religion would tell you that you have a better life waiting for you once you die and go to heaven. There has been no evidence that shows any sign of there being an afterlife, or a heaven for that matter. However, we do know that this life we are all experiencing right now is 100% guaranteed to us. Why not make the most of the life that is 100% guaranteed to you rather than living in hopes of there being a "better life" once this one is done??
Our present life is not "100% guaranteed to us". Just the opposite, in fact. It is 100% guaranteed that our present life will not last. All of us will die, and none of us know when. Even if you are young and apparently healthy, there could be a fatal genetic defect lurking in your DNA that will kill you. Some people die of genetic defects that they were completely unaware of until the moment of their death. You may not live to the end of this day. You may die before you finish reading this post.
Now--assuming you're still with me--I think the question you asked should be turned around. What's the point in being a wordling and living only for worldly pleasures, rather than living for the world to come that Jesus promised us. I was an atheist until age 23 and sampled almost everything that the secular world has to offer: money, physical pleasures, intellectual achievement, and more. All of these things only made me unhappy. So by choosing to follow Jesus, I gained everything in this world and lost nothing. If His promise of eternal life is true, I have also gained eternal life. If Jesus was actually some con-man and his promises were false, I've lost nothing.
16 The ground of a certain rich man yielded an abundant harvest. 17 He thought to himself, What shall I do? I have no place to store my crops. 18 Then he said, This is what Ill do. I will tear down my barns and build bigger ones, and there I will store my surplus grain. 19 And Ill say to myself, You have plenty of grain laid up for many years. Take life easy; eat, drink and be merry. 20 But God said to him, You fool! This very night your life will be demanded from you. Then who will get what you have prepared for yourself?" [Luke 12:16-20]
