Each of us is incomplete compared to someone else - an animal's incomplete compared to a person... and a person compared to God, who is complete only to be imaginary.
To place oneself in the position of God is painful: being God is equivalent to being tortured. For being God means that one is in harmony with all that is, including the worst. The existence of the worst evils is unimaginable unless God willed them.
Look at the Afghans, during the time of the Soviet invasion. They were among the poorest Muslims in the world, yet they were sustained by their faith in God, and God alone.
Jews have God's promise and if we Christians have it, too, then it is only as those chosen with them, as guests in their house, that we are new wood grafted onto their tree.
It may be that when the angels go about their task praising God, they play only Bach. I am sure, however, that when they are together en famille they play Mozart.
Man can certainly flee from God... but he cannot escape him. He can certainly hate God and be hateful to God, but he cannot change into its opposite the eternal love of God which triumphs even in his hate.
