Belief in the eternal directly influences current life. This life is limited - I will die. And I believe there is an afterlife that is eternal.

Apostle Paul’s words apply to everyone, not just the rich:

“Command those who are rich in the things of this life not to be proud, but to place their hope, not in such an uncertain thing as riches, but in God, who generously gives us everything for our enjoyment.

Command them to do good, to be rich in good works, to be generous and ready to share with others.

In this way they will store up for themselves a treasure which will be a solid foundation for the future.”

(1 Timothy 6.17-19 GNB)
