Read Matthew 6:9
There is something so beautiful about the faith of an innocent child, lifting up his or her heart to God in prayer. Do you remember in your own life as a young child just talking to God as if He were right there besides you? We soon pass from the “now I lay me down to sleep” stage in our praying and become aware of the need in our hearts to communicate daily with our heavenly Father. We become aware of the little sins that creep into our lives and understand the need to confess our sins and ask for forgiveness. We began to pray for others. Then, often, we would begin with a long list of petitions and favors we wanted from God. As children, these innocent moments of communication with our Heavenly Father opens the door of worship as we learn to express our love for Him in praise and adoration.
The “model” prayer of our Lord was not meant to be a prayer of rote memory, but a pattern for us to follow. Matthew 6:9, from the beginning, emphasizes the intimacy which we feel as we approach the throne of God in prayer. We see Him as “our Father” (Abba) and He recognizes us as His children. (Mark 14:36, Romans 8;15, Galatians 4:6).
“Who art in Heaven” does not confine God to heaven alone. We understand that God is everywhere. But it does distinguish Him from our earthly fathers. He is our Abba.
