Rejoice and be glad

Israel, heaven and earth, the islands are to “rejoice and be glad” in Yahweh (Psalms 14:7; 16:9; 31:7; 32:11; 97:1, 8).  The combination of terms is used in liturgical contexts; rejoicing and being glad is an act of worship.

Then Proverbs 23:24-25: Father and mother rejoice and are glad in a wise son.  Father and mother offer a kind of “liturgical” praise to their wise children.

And so in the fellowship of the Trinity.  The Father rejoices and is glad in the Son, and “mother” Israel joins in the Father’s praise.   The Son is the chief liturgist of the church, bring the church to worship the Father.  But there’s a reverse movement too, as the church joins in the Father’s eternal praise of His beloved Son.
