For many, perhaps most, God as Father is not a pleasant parallel, and because of this much of the Bible is difficult to grasp. Through the work of Jesus on the cross, we are made God's children, and God is a Father unlike any other.
Many of us think that Christian service is motivated by obligation, and this might have been true for Moses, but for Jesus it was love, because God is a good and perfect Father.
When I read these verses, they were illuminated with the truth and beauty of God's love and how it motivates us to service and faithfulness. The analogy, the parallel, of God as Father works for me because my dad loves Jesus and has for as long as I can remember.
Thank you, Father of all fathers, God who loves His children deeply, for Your graciousness in giving me a dad who loves You.
