The Fixed Center
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.’ (A.W. Tozer, The Pursuit of God, p. 51).
