Psalm 103 both begins and ends with the words, “Bless the Lord, O my soul.” It’s a common theme running throughout the Psalms. And there are many reasons suggested as to why we should continually bless the Lord.
In this Psalm while there are several reasons named, there is one that dominates. And that one is the Lord’s mercy. Note the following:
“The Lord is merciful and gracious, slow to anger, and plenteous in mercy. He will not always chide: neither will he keep his anger forever. He hath not dealt with us after our sins; nor rewarded us according to our iniquities. For as the heaven is high above the earth, so great is his mercy toward them that fear him. As far as the east is from the west, so far hath he removed our transgression from us. Like as a father pitieth his children, so the Lord pitieth them that fear him. For he knoweth our frame; he remembereth that we are dust.” (Psalm 103:8-14)
An appreciation of the riches and extent of God’s mercy toward us should make us all want to say with the Psalmist, “Bless the Lord, O my soul.”
