For Christians, theologically speaking, life only has value for the impact it has on eternity. Now, this is an imaginary concept. For the future never arrives.

Firstly, there is no life after death, as all atheists know.

Even if there were, what are you going to be doing in heaven? Planning for the future again? Living for the hope of eternity again? Once you reach heaven there is nothing more to hope for. Heaven is a hopeless place. All desires end there.

Sure you still want to aim for heaven?

Say you get all you want in heaven. There is nothing more. You already have all you want. All hope is lost. All hope has been vanquished. You would be as good as dead, and indeed you are, for you are in heaven.

In light of all these concepts, the present has very little meaning for the serious Christian. It’s rather depressing; it explains why very many Christians commit suicide, in spite of the hope of heaven. After all, everything here is only temporary in their eyes.

If you’re fat, it doesn’t matter. You will be thin in heaven. If you’re poor, you will be rich, so why bother to strive? In fact, striving might even bring the opposite effect, for it is more difficult for the camel to go through the eye of a needle than for the rich to enter into heaven. So being rich might even land you in hell. (You can also refer to the parable of the rich man vs Lazarus.)
