Isaac Watts (PHH 155) first published this baptism hymn in his Hymns and Spiritual Songs (1707). The Psalter Hymnal has omitted Watts's original third stanza and has altered the text considerably to update the language. Originally the first line read 'Thus saith the mercy of the Lord."
The song's four stanzas in the Psalter Hymnal are a "sung theology" of God's covenant with Abraham and his descendants (Gen. 17:7) expressed in the context of baptism. Stanza 4 offers an unusual apocalyptic view of the meaning of baptism.
Liturgical Use:
Most often for infant baptism.
