Jesus taught us, on the one hand, to pray to God as our Father.
Jesus taught us, on the other hand, to pray to God as our Father who is in heaven.
Whatever else that means, it surely means that in our approaching of God in prayer we should remember that God is high and lifted up, that God is exalted and holy, and that God is not at our beck and call.
It is God that we approach in prayer and God should be approached with awe, respect, and reverence.
Never let us forget when we are praying, O God, to whom we are talking.
“Our Father in heaven…” (Matthew 6:9b)
