As there is still a temptation to give a divided heart to God, so there is still a temptation to seek the help of some visible representation or symbol of God's presence in his worship. The Christian believer does not bow down to an idol, but many a Christian believer thinks that his mind can be helped upward in worship by looking at some representation of his Saviour's face, or at some symbol of his Saviour's passion. But just because God is infinitely above all material representations and symbols, so God can best be apprehended and discerned spiritually. Anything coming between man's spirit and God the Spirit is a hindrance to worship, and not a help to it. Suppose a young man were watching from a window for his absent mother's return, with a wish to catch the first glimpse of her approaching face. Would he be wise, or foolish, in putting up a photograph of his mother on the window-pane before him, as a help to bearing her in mind as he looks for her coming? As there can be no doubt about the answer to that question, so there can be no doubt that we can best come into spiritual communion with God by closing our eyes to everything that can be seen with the natural eye, and opening the eyes of our spirit to the sight of God the Spirit. This, again, is no arbitrary requirement of God; it is in the very nature of his being and of our own. The third requirement of this compact is, that there shall be no insincerity on the part of God's covenant people in their claiming and bearing his name, as the name of their covenanting God. This requirement is not generally understood in this light; but all the facts in the case go to show that this is its true light. In the Oriental world, and in the primitive world everywhere, one's name stands for one's personality; and the right to bear one's name or even to call on one by his personal name, is a proof of intimate relation, if not of actual union, with him. God was now covenanting with this people to be his people, thereby authorizing them to bear his name, and to be known as his representatives. In the very nature of things, this laid upon them a peculiar obligation to bear his name reverently and in all sincerity.
