The book of Psalms is a book of poetry. As long as people have had hearts, they have written poetry-using words to convey the depths of their experiences, sentiments, and thoughts. The Psalms are the same; they express a multitude of feelings from many people arising from their real walks with God. They speak out praise to God, accusation of the enemy, resentment of evil ones, blessings to the righteous, criticism of man, and self-evaluations. But the Psalms are also different, expressing not just human feelings but also God's speaking. There is one Psalmist writing the Psalms-God Himself. The voice of this Psalmist rings out through the praises of David, the sighings of Moses, the prayers of Solomon, the yearnings of the sons of Korah, and the aspirations of many anonymous writers.

In this work, Titus Chu expounds the Psalms in view of the divine experiences portrayed within. Book One, "The Growth of Life," shows the rich growth of the divine life in a revived believer. Book Two, "The Church Life," is about the sweet church life as each saint is growing. Book Three, "The Building of the Church, "reveals the experiences of everyone living in the church life, both positive and negative. Through the experiences in Book Three, God gains the built up church through those who are pure, and Book Four covers, "The Testimony of Life." Finally, out of the experiences of all these psalms comes Book Five, "The Praise of the Church." This commentary has not been compiled merely for readers to have a better understanding of Psalms. Rather, it aims to shepherd those who are in Christ and desire to grow in the divine life. May it bless the hands of the generation of those who seek God!

Hallelujah! After a long journey, the psalmist has led us to the end. Here, we use all our voice to shout, "Hallelujah! Let everything that has breath praise the Lord!" This is a happy ending. If there is a purpose for human life or for the universe to exist, then it is revealed right here: to praise God and to exalt the Lamb of God. After the experiences of the first four books of Psalms, which includes the growth of life (Book One), the church life (Book Two), the building of the church (Book Three), and the testimony of life (Book Four), the psalmist and the church, with accompaniment from all instruments, sing praises to God: "Hallelujah!"

Dear readers, for these many books of Psalms, from Book One to Book Five, we can only give thanks to God and praise Him. Hallelujah! What a Hallelujah this is!
