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. PackerThe Christian's instincts of trust and worship are stimulated very powerfully by knowledge of the greatness of God. But this is knowledge which Christians today largely lack: and that is one reason why our faith is so feeble and our worship so flabby... When a person in the church, let alone the person in the street, uses the word God, the thought is rarely of divine majesty.
J. I. PackerThere is a tremendous relief in knowing that {God's} love to me is utterly realistic, based at every point on prior knowledge of the worst about me, so that no discovery now can disillusion Him about me, in the way I am so often disillusioned about myself, and quench His determination to bless me.
J. I. PackerGod is triune; there are within the Godhead three persons, the Father, the Son and the Holy Spirit; and the work of salvation is one in which all three act together, the Father purposing redemption, the Son securing it and the Spirit applying it.
J. I. PackerOur aim in studying the Godhead must be to know God himself better. Our concern must be to enlarge our acquaintance, not simply with the doctrine of God’s attributes, but with the living God whose attributes they are.
J. I. PackerThe whole story of the Father's Christ-exalting plan of redeeming love, from eternity to eternity, must be told, or the radical reorientation of life for which the gospel calls will not be understood, and the required total shift from man-centeredness to God-centeredness, and more specifically from self-centeredness to Christ-centeredness, will not take place.
