Piper has a great blog post over at Desiring God:

Man is great. But compared to God’s greatness, “What is man that you are mindful of him?” The universe is designed to remind us of this distance between’s God’s infinite greatness, and man’s finite greatness. Man must reside on tiny planet earth in a seemingly infinite universe. And the universe must look infinite to be a fitting picture of what it cannot be: infinite. Only God is infinite. The universe is declaring that. Pretty well.

I was thinking about this as I flew to Maryland last September. As we flew overhead, all things that seemed significant while on the ground all of the sudden become small and insignificant. I asked the very questions this post addresses and the Lord answered me.

We are so affected by what we can perceive physically, that we cannot perceive spiritually unless we really work at it (oh and the Holy Spirit make this possible, by the way). This again demonstrates how we depend on the Word to live by faith. When taken purely on what we can perceive, we deceive ourselves from the truth. How amazing is it that God has made us “a little lower than the heavenly beings and crowned [us] with glory and honor.”? If we trust God’s Word to be true, we realize we are utterly insignificant in scale, but completely significant in worth to God because He has made us so.
