Praying to God as “Father” reminds us that we pray on the basis of our relationship with God. Our relationship with God is a love relationship, not a legal relationship. God desires an intimate relationship with us.
Prayer is one of the vehicles at God’s disposal by which he can demonstrate who he is. In John 14:13, Jesus said, “And I will do whatever you ask in my name, so that the Son may bring glory to the Father” (NIV).
Jesus taught that we are to “hallow” the name of our heavenly Father. To hallow God’s name is to ascribe reverence, respect and awe to God’s name (cf. Exodus 20:7). In the Old Testament, Jews attributed such reverence to God’s name that they would not speak or write it. God’s proper name is Yahweh, which means “I AM THAT I AM.” Another important name for God is Adonai, which means, “The Lord God.” Out of reverence, the Jews took the consonants out of Yahweh and the vowels out of Adonai to form the word “Jehovah.” You can always recognize the Hebraic use of Yahweh in the Old Testament when you see the word “LORD” in capital letters.
So what does it mean to hallow God’s name? The word hallow finds its root in the Greek word hagiazo. The noun form of the word, hagios, gives us the word “holy.” Therefore, to hallow God’s name means to revere and speak his name with reverence.
