In determining relationships we must begin somewhere. There must be somewhere a fixed center against which everything else is measured, where the law of relativity does not enter and we can say “IS” and make no allowances. Such a center is God. When God would make His Name known to mankind He could find no better word than “I AM.” When He speaks in the first person He says, “I AM”; when we speak of Him we say, “He is”; when we speak to Him we say, “Thou art.” Everyone and everything else measures from that fixed point. “I am that I am,” says God, “I change not.”
As the sailor locates his position on the sea by “shooting” the sun, so we may get our moral bearings by looking at God. We must begin with God. We are right when and only when we stand in a right position relative to God, and we are wrong so far and so long as we stand in any other position.
