The text alludes to the apocryphal book of Ecclesiasticus 50:22-24 (part of the Lutheran Bible), which reads: "Now bless the God of all, who in every way does great things," Stanza 1 thanks God for, what he has done in the past; stanza 2 prays for God's guidance in the future; stanza 3 is a Trinitarian doxology styled after the "Gloria Patri." Stanzas 1 and 2 were originally meant to be sung as a table grace; stanza 3 was added later as a Trinitarian doxology. (Stories that Rinkart wrote his text for the Peace of Westphalia of 1648 are incorrect, although this hymn was used in the celebrations of that year.)

The God who was active in providing his Son for our redemption, has also been active in the course of history and in the lives of his people. His activity in the course of history began when he created all things. Belgic Confession, Article 12 teaches that God, “when it seemed good to him, created heaven and earth and all other creatures from nothing, by the Word—that is to say, by the Son.” In addition, “God created human beings from the dust of the earth and made and formed them in his image and likeness.”
His activity also includes his constant care for all he has created. “…He watches over us with fatherly care, sustaining all creatures under his lordship” (Belgic Confession, Article 13). Additionally, God reveals himself by this “creation, preservation and government of the universe, since that universe is before our eyes like a beautiful book...” (Belgic Confession, Article 2).
We also believe that God’s mighty acts are revealed “in the unfolding of covenant history…witnessing to the news that Our World Belongs to God and he loves it deeply” (Our World Belongs to God, paragraph 33). Primary among these actions in the unfolding of covenant history is “the long road of redemption to reclaim the lost as his people and the world as his kingdom” (paragraph 18). As God’s people observe his work in their lives and in history they respond with praise and adoration.
