If you do not believe in eternity.
Then your life would not have purpose.
Your daily life would be pointless and soon forgotten.
This allows you to make your own subjective measure of what is good.
No need to take life seriously.
Party, because you will not matter in a few years anyway.
If you do believe in eternity.
Then you have been created to do something important both now and in all of time to come.
Your daily life’s decisions will build to a forever memorial.
This allows you to relax and follow Him who determines what is good.
No need to toil, just listen to Him.
Follow, because you matter, forever.
