In Psalm 1 we saw the righteous man, delighting in the law and the normal results of the earthly government of God as to just and unjust. Then Psalm 2 declared that, spite of all the world, He will bring in His incarnate Son, and set Him as king on the holy hill of Zion; the latter exhibiting the counsels, as the former did the governmental principles, of God. Psalms 3-7 express the exercises of the godly amongst the ungodly who are in power. In these psalms, consequently, we hear the righteous remnant looking for the Lord's coming in judgment to sustain their faith and make good His word; but they pass through every sort of trial, for the circumstances suppose that Christ is not reigning over the earth, and that evil is not yet judged. God is standing back as it were; nevertheless He turns these trials of circumstances and exercises of heart of the godly to their profit, a blessing much deeper than if the judgment fell at once on the ungodly.
Psalm 8 is of another character. Jehovah is to be glorified in the earth, as well as His glory to be set above the heavens. As a whole, we know this has not been yet. The Father's name has been declared, and is now, to the hearts of the children. The Son of man is glorified, and God is glorified in Him. But never yet has the name of Jehovah become excellent in all the earth. Our psalm announces that it is to be universally glorified here below. It will be when Christ takes the government of the universe. But this depends on His coming (1 Cor. 15), when the dead saints rise, and the living saints are changed. He is head over all things to the church, which is His body (Eph. 1). This we do not yet see with our eyes; but we do by faith see Jesus already crowned, the witness and pledge of all the rest (Heb. 2). The church meanwhile is being gathered. When He enters on the kingdom, we shall come and reign with Him. The only thing in which, as a Christian, I can separate myself from Christ, is where He was made sin. To look at His glory is to look at our own; and He, the glorified man, is exalted above all creatures, and has dominion over all the works of God's hand.
From Luke 9 we learn, that, being morally rejected as the Christ or Messiah, Jesus would not set Himself up as king. Then He takes another title - "Son of man," and as such, He must suffer. He does not permit that He should be proclaimed any more as the Christ of Psalm 2, but falls back on the name of "Son of man," as in Psalm 8. He must suffer before the glory, and be exalted in heaven, before He takes the earthly crowns. "Except a corn of wheat fall into the ground and die, it abideth alone; but if it die, it bringeth forth much fruit." As Son of man, He is to have all things under Him, and not merely the throne of Zion. That is to be accomplished too; but, according to Isaiah 49, He is to have the Gentiles also. Yea, God will gather together in one all things in Christ, whether things on earth or things in heaven; and we shall be the heavenly Eve of the last Adam - the Lord from heaven. In the Psalms we find the Christ we are associated with, but not our association with Him. The scheme of divine government there supposed has not yet begun. Christ is to be king, and this over the earth. Psalms 2 and 8 are prophetic. He has not yet broken the nations with a rod of iron. His anger is to fall on the rebellious kings before the predicted reign of blessing commences. We are now, as it were, associated with Aaron in the sanctuary, before He comes out to the deliverance and salvation of His earthly people.
