In this manner, therefore, pray: Our Father in heaven, hallowed be Your name. Matthew 6:9
Approaching the throne of God in prayer is simple and yet it is complex. When we pray, we are told to address our petition to “our Father in heaven.” For those of us who have had a wonderful father here on earth, that instruction gives a clear connection on how to approach our Father in heaven. And yet, we are also addressing our supplication to the Creator and Lord of the universe—the One who made all things, including us.
Because He loves us, we can address Him as “Father.” The Aramaic Abba might be used by a young child addressing his father as “Daddy.” But because of Who He is, we are to approach Him with reverence. We must not in any way diminish His glory or presume when we pray, “For the LORD Most High is awesome; He is a great King over all the earth” (Psalm 47:2). Someday we will be at home with our Father in heaven—it is a thought too wonderful to fully imagine—but until that day, we have the privilege of approaching “Our Father in heaven” through prayer.
Humble prayer to our heavenly Father, in deep faith in Jesus Christ, is essential to qualify us for the companionship of the Holy Ghost. Henry B. Eyring
