Daniel 5:29-31 (ESV)
 Then Belshazzar gave the command, and Daniel was clothed with purple, a chain of gold was put around his neck, and a proclamation was made about him, that he should be the third ruler in the kingdom.
 That very night Belshazzar the Chaldean king was killed.  And Darius the Mede received the kingdom, being about sixty-two years old.
The glory of man is short-lived at best. Daniel was clothed with royal clothing, given a gold chain to wear, and made third in the kingdom. He would have been the envy of every wise man, counselor, and noble in the kingdom. Yet Daniel knew that it meant nothing. By morning it was all gone. Babylon had fallen to Persia. Whatever glory the Babylonian king had conferred on Daniel was meaningless. There was a new king in town.
The world has not really changed. People are still vying for wealth and attention. But it is short-lived. The idols of my youth are now dead or old. There are new idols, new gods of the media, new “beautiful people.” But it won’t last. So many die young. The few that live to old age often live in emptiness with little hope or meaning. The glory of this world is fleeting. The wealth of this world cannot stop the process of death that grips us all. We strive for a big house only to discover that we don’t need all that room anymore and it is too much to take care of. We strive for wealth only to give it all to the medical professionals. We work hard to stay healthy only to discover that eventually our health fails us. The glory of this world fades, and it fades quickly.
Belshazzar was king. Much of the known world was under his control. He felt secure in his position. He reveled in his glory and wealth. Then a hand wrote on the wall, and by morning he was dead. Ecclesiastes is right. In Ecclesiastes 2:17-19 Solomon wrote,
So I hated life, because what is done under the sun was grievous to me, for all is vanity and a striving after wind. I hated all my toil in which I toil under the sun, seeing that I must leave it to the man who will come after me, and who knows whether he will be wise or a fool? Yet he will be master of all for which I toiled and used my wisdom under the sun. This also is vanity.
If the wealth and glory of this life are all that we have then what is the point? It will all turn to dust one day. Someone will sort through our stuff. They will hoard it, sell it, or throw it in the trash. One man told me he was buying stuff and storing it in his garage so that when he died his kids would have to get rid of it. If that is the biggest goal we have in our hearts, to amass stuff in order for someone else to get rid of it, we have too small a goal. If that is all our lives are about then we have too small a life. We have learned nothing from Nebuchadnezzar, Belshazzar, and Daniel.
What are you giving your life to? Temporal stuff or eternal value? Learn from Daniel. Let us humble our hearts before God and pursue only that which lasts for eternity. What are you giving your life to?
