Psalm 49 - Wealth is Worth Nothing.

Psalm 49 deals with what happens after death for those who ignore God and those who follow Him.

People, despite their wealth, do not endure;

they are like the beasts that perish.

This is the fate of those who trust in themselves,

and of their followers, who approve their sayings.

They are like sheep and are destined to die;

death will be their shepherd

(but the upright will prevail over them in the morning).

Their forms will decay in the grave,

far from their princely mansions.  Verses 12-14

It is very sad that so many will choose selfishness and independence from God only to die an eternal death. (For the living know that they will die, but the dead know nothing; they have no further reward, and even their name is forgotten. Eccl. 9:5) It says here they, "trust in themselves" and not God. 

But God will redeem me from the realm of the dead;

he will surely take me to himself.

Do not be overawed when others grow rich,

when the splendor of their houses increases;

for they will take nothing with them when they die,

their splendor will not descend with them.

Though while they live they count themselves blessed—

and people praise you when you prosper—

they will join those who have gone before them,

who will never again see the light of life.

People who have wealth but lack understanding

are like the beasts that perish.  Verses 15-20

In the eyes of God, wealth is worthless unless you use it to help others. The trouble with being rich is it gives one a feeling of security and some happiness. It would be hard for a person to learn to sacrifice if they are wealthy. It is easy to trust in riches and be proud of prosperity. That is why Jesus said it was hard for a rich man to enter the kingdom of God.
