The Third Book: Discernment of the true good (Psalms 72-88)
The third section of the Psalter encourages us to lift ourselves from everything that materially binds us so that we can continue our spiritual ascent. With the help of Spiritual enlightenment, a man can understand things that are unfathomable.
St. Gregory of Nyssa further says that we should not be troubled by earthly deeds, but we should keep His Second Coming in our minds so we can prepare ourselves to attain God's love.
The first part of Psalm 72 presents the Prophet’s dilemma about accepting the good, while evil seems to prosper. The last verses of the Psalm provide hope for those who have made the right decision.
"For my heart was fired and my reins have been changed, and I was brought to naught and knew it not. I became as a beast before Thee, and I am ever with Thee"
We often forget that the righteous man never lacks divine assistance. Understanding these Psalms shows us how pitiful our concerns are about earthly things.
The Fourth Book: The denunciation of vanity (Psalms 89-105)
These Psalms take us to a level higher than the previous Psalms. Once we start to understand the Psalms and reach practicing asceticism all the things we do will be done clinging to God, according to Gregory of Nyssa.
St. Gregory recounts all the wonderful accomplishments of Moses and describes him as the mediator and intercessor for the mutable and immutable natures and interceding for both extremes. He offers prayers to God and asks God’s mercy upon those in need.
The Psalmist asks God to extend His hands over our fallen human nature, and to help us humble ourselves from the loftiness. God does not want to dominate us, so he gave man free-will to make his own decisions. Because of our fallen nature we tend to sin, but God calls us to repent.
In order to be enlightened we must follow the teachings of the Orthodox Church, which help us to avoid earthly things and commit ourselves to the pursuit of greater, spiritual achievements.
The Fifth Book: Summation of salvation (Psalms 106-150)
St. Gregory of Nyssa describes through Psalms our journey towards salvation. We as followers of Christ need to seek good and remember that God will definitely help us to reach the goal.
"Let everything that hath breath praise the Lord. Praise ye the Lord." (Psalms 150:6)
The Psalter ends by showing us that when human nature has attained its end, the reunion of Angel’s and men will accomplish the thanksgiving in its Ultimate. The Psalm 150 for the summit of salvation. Sin separated us from the angels, but once we reach the summit of ascension, we will again be united with them and with one voice praise God.
The constant repetition of the Psalms makes them part of our daily lives. They start to express our sorrows, joy, and our heartfelt prayer. They also unite us with one another letting us share in the deepest yearnings, the anguish and the joy, who hear God's call to life more abundant.
The Psalter has always helped me in the time of need, worry, and concern. This collection has further helped me to get closer to God, by understanding how loving our God is.
