This collection of Psalms, most considered to be authored by David, summarize the greatness of God, and what our relationship with Him should be like. Chapters 8, 19, and 23 declare the greatness of God. Chapter 104 is a song of appreciation and declaration that He is our source of joy. Lastly, Chapter 137 depicts a time when the love and shepherding of God should be sought. These selections from the book of Psalms assure us that we are worthy creations of God, and that He is always there to sustain and care for us.
Chapter eight is a song of praise to God, because He created man. David expresses his wonderment that God would bestow such a blessing, "What is man, that thou art mindful of him? And the son of man, that thou visitest him?" (88) David praises the fact that despite our unworthiness, God loves us enough to have made us, and to give us dominion of the rest of His creation. .
Chapter nineteen praises the greatness of God, evidenced in all of creation. Again David sings praises to God that His greatness is revealed throughout creation. "The heavens declare the glory of God; and the firmament sheweth his handywork. Day unto day uttereth speech, and night unto night sheweth knowledge. There is no speech nor language, where their voice is not heard." (88) Here also is David's request that God help him in his effort to be sinless before God.
Chapter 23 is a song of honest and open love for God. This chapter shows us that He is our only hope for eternal life and security. "The Lord is my shepherd; I shall not want." (89) This verse shows us that when we allow ourselves to be shepherded, that is cared for by God, that every need of ours is guaranteed to be met. David realizes that a walk with God does not guarantee a life devoid of struggle or conflict, but that with God as our guide we should remain in peace knowing that God is always with us. "Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me.
