James 1:11

For the sun rises with scorching heat and withers the plant; its blossom falls and its beauty is destroyed. In the same way, the rich man will fade away even while he goes about his business.
(NIV)

The reality that is being taught here is not just directed at the rich. As the Psalmist says,

You have made my days a mere handbreadth; the span of my years is as nothing before you. Each man's life is but a breath.
Psalm 39:5 (NIV)

This applies to us all. Our lives are passing so quickly, and our glory should not be in what we accomplish here. A big house, an established retirement account, a new car, even our kid's educations paid for! All of these things are temporary. One day you will breathe your last and these things will all be gone.

Let your glory be in Christ. Let your glory be in what He has done in you. Don't glory in what you can make with your own hands. If you do, then you are no different than an idol maker who sits and carves out his idol, then turns around and bows to it.

Even the poor man shouldn't glory in his lack of goods. There are some like that who talk about how they don't have all of that stuff, and speak about the new cars and the big house like they were worldly in and of themselves. You are missing the point if you are saying that.

It is all about Jesus Christ. It is all for His glory. Everything in our lives should point to Him.
