In Isaiah 12 he offers his personal hymn of praise. It is a great description of the joy the people will have when Jesus Christ comes to reign over the earth.
Rather that providing reflections on this passage, I will just let you read it for yourself…
Isaiah 12:1-6 NLT
 In that day you will sing: “I will praise you, O LORD! You were angry with me, but not any more. Now you comfort me.  See, God has come to save me. I will trust in him and not be afraid. The LORD GOD is my strength and my song; he has given me victory.”  With joy you will drink deeply from the fountain of salvation!  In that wonderful day you will sing: “Thank the LORD! Praise his name! Tell the nations what he has done. Let them know how mighty he is!  Sing to the LORD, for he has done wonderful things. Make known his praise around the world.  Let all the people of Jerusalem shout his praise with joy! For great is the Holy One of Israel who lives among you.”
