The world was not created aimlessly but is full in amusement of delusion, only when you start to do good, do you then see the further good in it but all of the good would be useless in the end if you do not believe in Him.
Except, that He would retain the good if you were to believe, and for those who would like to, He converts what He wills.
There is no fun in the world unless it is of that short-lived, invest in the hereafter, where everything lasts forever, not ever would you want transfer from it.
Fun for everyone who has the Heaven as an abode, what should you work for in the world?
The World we are yet to know.
