His infinite knowledge, from the heat of which nothing is hid, has no stages of advancement, and no events lying nebulous in a dim horizon by reason of distance, or growing in clearness as they draw nearer, but which pierces the mists of futurity and the veils of the past and the infinities of the present, and 'from the beginning to the end knoweth all things.' It is the assurance that the mighty stream of love from the heart of God is not contingent on the variations of our character and the fluctuations of our poor hearts, but rises from His deep well, and flows on for ever, 'the river of God' which 'is full of water.' It is the assurance that round all the majesty and the mercy which He has revealed for our adoration and our trust there is the consecration of permanence, that we might have a rock on which to build and never be confounded. Is there anywhere in the past an act of His power, a word of His lip, a revelation of His heart which has been a strength or a joy or a light to any man? It is valid for me, and is intended for my use. 'He fainteth not, nor is weary.' The bush burns and is not consumed. 'I will not alter the thing that has gone out of my lips.' 'By two immutable things in which it is impossible for God to lie, we have strong consolation.' II. The unchanging God as the foundation of our changeful lives. In the most literal sense our text is true. Because He lives we live also. He is the same for ever, therefore we are not consumed. The foundation of our being lies beyond and beneath all the mutable things from which we are tempted to believe that we draw our lives, and is in God. The true lesson to be drawn from the mutable phenomena of earth is--heaven. The many links in the chain must have a staple. Reason requires that behind all the fleeting shall be the permanent. There must be a basis which does not partake of change. The lesson from all the mutable creation is the immutable God.
