The Psalms end with a doxology calling all to praise God. When we praise God together we are reminded that all creatures of our God and King in Heaven and Earth are united in praising God for who he is and what he has done. The mightiest deed of God that the psalmist had known was the Exodus, and even this pales in comparison to the glory of the cross. We praise God for coming in the flesh through the form of Jesus, and dying on the cross for our sin in an indescribable act of love and mercy. We praise God with our whole being, gathering all the available musical gusto to praise his name in church. Yet, worship is a daily thing, and our lives are to be lived in worship of him.
