Our Scripture reading today is Daniel 4:30-32.
Verse 32, "...until thou know that the most High ruleth in the kingdom of men, and giveth it to whomsoever he will."
King Nebuchadnezzar was about to learn just Who really was responsible for building the great Babylon.  He is clearly lifting himself up and is about to be brought low.  
These verses are a good reminder to each one of us of the importance of recognizing we are not self made individuals.  We did not make ourselves successful in business.  We did not build our family.  It is only by God's grace that we are not only saved, but that we are able to live each day for His glory.  The Word of God tells us to humble ourselves and God will left us up in His time.  Read James 4:10 and 1 Peter 5:6.
