"O LORD, our Lord, how excellent is Your name in all the earth!"
Earlier in this Psalm, David had marveled that God even paid any attention to, or respect to mankind. Now, David gives God--not man--the ultimate expression of praise. It is "The Lord" whose name is "excellent"--even in "*all* the earth!"
There is not a square inch of this planet, where God's name is not excellent. Mankind has corrupted the whole world through the Fall (of Adam); but the Lord has restored and given hope to it in the atonement and resurrection of the Last Adam (Christ). For this blessed fact, let us give thanks and praise to God.
[Puritan quote of the day: "Hence we learn that we must not pass too harsh judgment upon ourselves or others when God exercises us with bruising upon bruising." --Richard Sibbes, in "The Bruised Reed"]
