What does the Bible say about the Psalms?

The Psalms are described as the epitome of the entire Gospel, capturing the essence of Christ's sufferings and the glory that follows these sufferings. They serve as a collection of prayers and songs that deeply express human experience while simultaneously revealing God's redemptive plan through Christ. As seen in passages like 1 Peter 1:10-11, the psalmist, under the inspiration of the Holy Spirit, articulated profound truths concerning Christ's redemptive work, emphasizing that the Psalms were written to signify the sufferings of Christ and the ensuing glory.
