The point here is not just that an image represents God as having body and parts, whereas in reality he has neither. But the point really goes much deeper. The heart of the objection to pictures and images is that they inevitably conceal most, if not all, of the truth about the personal nature and character of the divine Being whom they represent.
J. I. PackerTo an age which has unashamedly sold itself to the gods of greed, pride, sex, and self-will, the church mumbles on about God's kindness but says virtually nothing about his judgment... The fact is that the subject of divine wrath has become taboo in modern society, and Christians by and large have accepted the taboo and conditioned themselves never to raise the matter.
J. I. PackerThere is tremendous relief in knowing that His love to me is based at every point on prior knowledge of the worst about me.
J. I. PackerDo I as a Christian understand myself? Do I know my own real identity? My own real destiny? I am a child of God, God is my Father; heaven is my home; every day is one day nearer. My Saviour is my brother; every Christian is my brother too. Say it over and over again to yourself first thing in the morning, last thing at night, as you wait for the bus, any time when your mind is free, and ask God that you may be enabled to live as one who knows it is all utterly and completely true. For this is the Christians secret of the Christian life, of a God-honouring life.
J. I. Packer
