V. May the Lord Give/May the Lord Bless [v.11]
God’s Sovereignty over all things, as He reigns eternally over all of creation, is mentioned first in vv.1-10, and then is followed by a prayer to the Lord to give peace and blessing to His people. David’s recognition of God’s Sovereignty over all of what He has created does not exclude humanity. It is the Lord who gives peace and blessing, and He gives it to His people. In the nationalistic context of this psalm, this is an immediate reference to the physical nation of Israel. However, for the church this reference is to all whom God has elected unto salvation, for as the Old Testament revelation teaches that God chose those over whom He would rule and reign by His Word spoken through His mediator (i.e. Moses), so He has also chosen all those over whom He reigns in the Person of His Son, the Lord Jesus Christ. Our Lord’s election of the physical descendents of Israel, therefore, is a picture, if you will, of His election of a people unto Himself from all nations and tribes and tongues.
Note that the Lord is the One who gives and who blesses and who possesses, not the creature. Man is subject to the rule and eternal reign of God, He is not subject to man’s delusions of grandeur. God is shown to not be under obligation to (a.)choose a particular people for Himself (chosen from out of all the nations of the earth), (b.)to grant them strength in their time of need, or (c.)to bless them in any way at all. Rather, God is the Sovereign Creator King who righteously sits as Elector, the One who Decrees all things whatsoever that come to pass, who retains the right to Judge, for He is absolutely perfect, and whose kingship will never be shaken, although all things may shake.
Creation is under obligation to give unto the Lord the glory and strength due His Name, and God is not under any obligation whatsoever to bless any of His rebellious creatures, as I’ve already mentioned. However, one small word in this psalm speaks volumes about the character of our Lord. That word is the word: “May.” It at once declares that God is Sovereign and retains the right to do whatever He wishes with His creation, while simultaneously teaching us that our Lord may be approached in prayer. He is Almighty and eternal, Omnipotent and Just, but He is also our Father who has loved us with an everlasting love, and who invites us to ask, in faith, for strength and peace. Christ’s church, the children of God, are taught in this one word to have confidence in Him to whom all things render obeisance, who is glorified in the destruction of the wicked as well as in bestowing His unmerited favor upon vile sinners who deserve only His everlasting fury and wrath.
 Cf. Deut 7:6-8
 Cf. 1 Peter 2:9-10
 This can also be found stated with clarity in the Old Testament (cf. Isa 2:1-4;
 The Voice of the Lord, in fact, has determined the outcome of all things – even the shaking and emptying of the earth (cf. Heb 12:27-29).
