In this great song of admiration, David extolls the excellence of the name of God. David surveys the majestic power of God in creation and His condescension towards man, celebrating the great love and kindness of God toward mankind, not only in man’s creation, but especially in his redemption by Jesus Christ. The Lord has ultimate dominion, but man was created in God’s image (Gen 1:26f) and for ongoing conformity to the image of Christ (Rom 8:29). Man was given dominion over God’s marvelous creation, which even little children acknowledge as truth (Matt 19:14; 21:15f)!
Certainly, if man is to take dominion and “rule over the works of [God’s] hands” by having “all things under [man’s] feet” including land animals, birds and fish, he must have many children. Such fruitfulness is required for such a vast undertaking of stewardship.
“1 ¶ « For the choir director; on the Gittith. A Psalm of David. » O LORD, our Lord, How majestic is Your name in all the earth, Who have displayed Your splendor above the heavens! 2 From the mouth of infants and nursing babes You have established strength Because of Your adversaries, To make the enemy and the revengeful cease. 3 ¶ When I consider Your heavens, the work of Your fingers, The moon and the stars, which You have ordained; 4 What is man that You take thought of him, And the son of man that You care for him? 5 Yet You have made him a little lower than God, And You crown him with glory and majesty! 6 You make him to rule over the works of Your hands; You have put all things under his feet, 7 All sheep and oxen, And also the beasts of the field, 8 The birds of the heavens and the fish of the sea, Whatever passes through the paths of the seas. 9 O LORD, our Lord, How majestic is Your name in all the earth!” (Ps 8:1-9 NAS95)
