This psalm is intended to direct yours and my thinking toward the vastness of this God and His majesty as compared to the puny insignificance of you and me. And yet that great, awesome God has it in mind - it is His purpose - to glorify Himself in us. Yes, out of the mouths of babes and infants. This is where that principle in I Corinthians 1:26 comes from. God has called the weak of the world - to glorify Himself in. He has chosen that which is weak and foolish (by this world's standards) to come to appreciate and to respect the glory of God - the glory that is in His name.
