Isaiah 12: The Lord Is My Strength and My Song

(6 verses, :53 to read)


What I am about to READ

  • A song of comfort and a hymn of praise.


  • v.1–We give thanks to the Lord in that day; but what is “that day”.  That day is today, for today is the day of salvation.  We should indeed receive nothing but wrath and anger from God and yet He has turned aside from that anger in order to comfort us.
    • The comfort of our God is nothing more than the forgiveness of sins; for where there is the forgiveness of sins, there is also life and salvation. (Luther’s Small Catechism)
  • v.2a–“This is a description of peace that comes after the forgiveness of sins has been received.  thus the heart stands firm, and this is proclaimed.  Now i have someone on whom I may rely and in whom I may trust, to whom I may look, namely, God, who no longer is angry and punishes but saves from every danger and evil.”  (AE 16:129)
  • v.2b–Isaiah takes this verse from the Song of Moses in Exodus 15:2 as the Israelites sing a song of praise to the One who saved them from the hands of the Egyptians.
  • v.3–“The water from the wells of salvation,” is nothing more than the very water flowing from the side of our Lord and Savior from the cross.  We draw this water as Christ gives us His cross in Word, Baptism, and the Holy Supper.
  • vs4-6–This is our song of thanks and praise.  It is a song of salvation; one that we sing at the top of our lungs.  Salvation belongs to none but God and He has given that salvation to His Church.
    • And so we make this salvation known.  The Holy One of Israel, the One who should indeed meet us with wrath and anger, now comes to us with words of Absolution on His lips, fleshly bread in one hand and bloody wine in the other; promising to drown our enemies of sin, death, and the devil in the raging waters of our Baptism.


  • This text can be heard on the 4th Sunday of Lent in the Three Year Lectionary and the 5th Sunday of Easter in the One Year Lectionary.  It can also be sung as the “Old Testament Canticle” in the Service of Prayer and Preaching in the Lutheran Service Book.
  • Sin deserves punishment and death. Sin brings upon the sinner the wrath of an angry God. And yet we have the promise, through Christ, that God has turned away from His anger towards us. He comfort us with the Gospel of the forgiveness of sins. This is pure joy: that we have in our midst the Holy One of Israel who comforts us with Words of Absolution, with a washing that makes us righteous, with a meal that make us one with Him. He is not far off seething in anger, but He is close at hand; close enough to hear and taste and feel upon our foreheads.
  • Holy One of Israel, You alone are our hope and salvation.  Although we have not deserved your mercy and grace, You have turned aside from Your anger in order that You might comfort us.  May we ever give thanks to You; shouting and singing for joy Your endless praises in all the earth, through Jesus Christ, Your Son, our Lord, who lives and reigns  with You and the Holy Spirit, one God, now and forever.  Amen.
