Or, Happy. Psalms is not a book of doctrines or of any kind of teaching. It is a book of divine revelation composed of the expressions, sentiments, feelings, impressions, and experiences of godly men concerning:
1) God and the way He is in His dealing with them;
2) the law of God as the holy Word with the divine revelation;
3) the house of God, the temple, and Mount Zion, on which the temple was seated, as the center of God’s dwelling place on earth;
4) the holy city of God, Jerusalem, as the encompassing protection of the house of God;
5) the holy people of God, Israel, as God’s beloved elect among the nations;
6) Israel’s love toward God, their fellowship with God, their blessings received of God, their sufferings under God’s dealings, and their environment;
7) their captivity;
8) their thanksgivings and praises to Jehovah their God, whom they tasted and enjoyed. Through the godly expressions of the psalmists Christ is revealed and the church as God’s house and God’s city is typified.
The Psalms were written according to two kinds of concepts: the human concept of the holy writers and the divine concept of God. The human concept of the holy writers was produced out of their good nature created by God, formed with the traditions of their holy race, constituted with the teachings of the Holy Scriptures, promoted by their practice of a holy life, and uttered out of their holy sentiments and impressions. The divine concept of God as the divine revelation in the Psalms concerns three major items:
1) God’s eternal economy, of which Christ is the centrality and universality;
2) Christ in His divinity, humanity, human living, all-inclusive death, life-imparting and church-producing resurrection, glorification, ascension, appearing in glory, and reigning forever;
3) God’s heart’s desire, His good pleasure, in Christ as His centrality and universality, in the church as His fullness for His expression, in the kingdom for His eternal administration, and in the recovery of the earth for His eternal kingdom in eternity.
In the Psalms only what is written out of the divine concept of God, and not what is written out of the human concept of the psalmists, should be considered as part of the divine revelation from God concerning His divine economy.
According to the divine concept, the central thought of the book of Psalms is Christ, as revealed in plain words (Luke 24:44), and the church as the house of God and the city of God for His kingdom, as typified by the temple and by the city of Jerusalem. The spirit, the reality, the characteristic, of the divine revelation in the book of Psalms is Christ as the centrality and universality of the eternal economy of God. For this, Christ is first the embodiment of the Triune God (Col. 2:9), then the house, the habitation, of God (signified by the temple — John 2:19-21), the kingdom of God (signified by the city of Jerusalem — Luke 17:21; Rev. 22:3b), and the Ruler of the entire earth from the house of God and in the kingdom of God (Dan. 2:34-35). Thus, He is all in all in the entire universe (cf. Eph. 1:23; Col. 3:11). Such a divine revelation is the same as what is revealed in the entire Holy Scriptures. The only particular point related to the divine revelation in the book of Psalms is that such a high revelation, even the highest peak of the divine revelation, is prophesied in the expressions of the sentiments of the ancient godly saints. Thus, it is mixed with their comfort in sufferings and with the cultivation of godliness. The consummation of this highest divine revelation is the city of New Jerusalem as a sign of the habitation, the tabernacle, of God (Rev. 21:1-3), through which the processed and consummated Triune God will be manifested and expressed in the all-inclusive Christ and will reign on the new earth in the new universe for eternity.
