This is a deceptive message - abandon all joys of this world for joys in next world. First of all nobody has any idea what actually awaits us in Christian heaven it's buying a cat in the bag. Second it sounds weird - learn to despise wealth and success and hapiness - bet then you get all these things given in heaven? Wouldn't heaven then look like torture to receive all these things you have trained yourself to hate?
This is why Nietzche correctly described Christianity as Sklavenreligion - it programs people to give away power in both this life and the next.
The true law of universe is: As Above So Below - if you choose to be miserable in this world you will be miserable in the next one too. If you choose to be be prosperous and generous in this life you will be in next too.
