The Large Catechism says, "To hallow means the same as to praise, magnify, and honor both in word and deed," (LC III 46). God's gifts and answered prayer give us an unsurpassed joy. I have joy that I know exactly who God is. I know His name. I know I am forgiven in His Son. I know His name is mine in Holy Baptism. I know that I am His beloved child. I know He expects me to sanctify His name in word and deed. I know He answers my prayer, "Hallowed be Thy name."
