Nebuchadnezzar, what a great man he must have been. He was one of extremes. In the book of Daniel we find him having a huge gold statue of himself built so everyone in his land could worship him. And then toward the end of his life he was praising God. In the middle of that time he was cast out of his kingdom by God Himself and lived like an animal for seven years. His hair became like feathers, his finger nails like claws.
The part of the verse in Daniel 4 I quoted above is said after Nebuchadnezzar recognizes who God is. Verse 34 says "At the end of that period (the seven years) I, Nebuchadnezzar, raised my eyes toward heaven, and my reason returned to me, and I blessed the Most High and praised and honored Him who lives forever;. . . (35) And no one can ward off His hand Or say to Him, What hast Thou done?'"
It is quite amazing Nebbi said this after his animal existence for seven years. His entire kingdom, everything was taken away and at the end of it we see his reason returning when he recognized God.
This touched me so much because sometimes I can get so caught in daily circumstance that I forget. I dwell on things I shouldn't dwell on. When things don't go how I think they ought, when I am believing so hard for something to happen and it doesn't, I can get discouraged, lost in my own lostness.
But when I remember God and who He is and what He can do and what He does for us in every nanosecond life, my reason, my understanding returns to me. God will tell us what we need to know. This life is on a need-to-know basis.
If He told us what was coming, it might freak us out pretty bad. It's better to walk step-by-step and day-by-day getting the strength and faith we need for today.
