Why do you work so hard on material things, if when you die you won’t take anything with you? There are many who accumulate wealth and become very attached to it, and when you die your body rots, worms eat your flesh and you do not take anything from this world to the next life.
It is evident that the human being is vain in a great way, his thoughts are only set on obtaining wealth, on having everything as much as he can, and they forget that God is in heaven and that one day their lives will come to an end.
There is a biblical verse that teaches us about those who only put their trust in riches and why we should not do that:
For when he dieth he shall carry nothing away: his glory shall not descend after him.
