Psalms Chapter 99 contributes to the biblical theme of prayer, praise, and the full range of human emotion before God, which Catholic teaching develops throughout the Catechism. the Psalms are the prayer book of the Church, prayed daily in the Liturgy of the Hours (CIC 2585-2589). The enduring truth that God invites us to bring all our emotions to Him calls us to response.
The Second Vatican Council's Dei Verbum teaches that "Sacred Scripture is the speech of God as it is put down in writing under the breath of the Holy Spirit" (DV 9). This chapter, like all Scripture, is inspired by God and profitable for teaching, reproof, correction, and training in righteousness.
Catholic tradition encourages daily engagement with Scripture, whether through the Liturgy of the Hours, personal reading, or group study. The Catechism teaches that "prayer should accompany the reading of Sacred Scripture, so that a dialogue takes place between God and man" (CIC 2653). May your reading of this chapter be a true encounter with the living God.
