The Divine motivation for some statements God makes will always be a mystery but occasionally, we are given a glimpse into the eternal Mind (Deuteronomy 29:29). Jehovah is not given to the common errors of communication with which humanity struggles, i.e., redundancy, contradictions, vanity, etc. When God states something there is a reason for it. The key to understanding His motivations is to allow Him to be His own commentator.
When Prophet Nathan went to King David, his message was this: “Would you build a house for Me to dwell in?” (2 Samuel 7:5). Solomon realized that His nature was too expansive, powerful and ethereal to be contained in a puny pile of bricks (1 Kings 8:27). Isaiah, however, gives commentary:
Thus says the LORD: ‘Heaven is My throne, And earth is My footstool. Where is the house that you will build Me? And where is the place of My rest? For all those things My hand has made, And all those things exist,’ Says the LORD.” (Isaiah 66:1-2a).
This statement seems like God is stating the obvious; but He is not given to vain communication. And, in this text we find at least one of His Divine motives for such a revelation: “But on this one will I look: On him who is poor and of a contrite spirit, and who trembles at My word” (v. 2b). Here we have it. The point God made to King David, King Solomon, Prophet Isaiah and to you and me is not so much the fact that God is great but that He employs that greatness in protection, care and love for those of a certain attitude: those who humbly submit to God (1 Peter 5:6); “for He cares for you” (vs. 7).
“Humble yourselves in the sight of the Lord, and He will lift you up” (James 4:10).
