I think that people dogmatise a great deal too glibly as to what they know very little about, the interaction of the divine and the human elements in Christ, and on the one side are far too certain in their affirmation that His humanity possessed in some reflected fashion the divine gift of omniscience; and on the other hand, that His manhood, passing through the process of human development, and increasing in wisdom, was necessarily in its earlier stages void of the consciousness of His Messianic mission. I dare not affirm either 'yes' or 'no' about that matter; but this I am sure of, that if ever there was a time in the development of the Manhood of Jesus Christ when He began to know Himself as the Messias, at that same time He began to be certain of the Cross. For His Messianic work required the Cross, and the divine thing that was in Him was born into the world for a double purpose, to minister and to die.
So, dear friends, putting aside mere metaphysics, which are superficial after all, we have to recognise this as the fact, that all through His career there arose before our Lord the certainty of that death, and that it did not assume to Him the aspect which such a prospect might have assumed to others as a possible result of a mission that failed, but it assumed to Him the aspect of the certain result of a work that was accomplished. He began His career with no illusions, such as other teachers, reformers, philanthropists, men that have moved society, have always begun with. Moses might 'suppose his brethren would have understood how that God by His hand would deliver them,' but Christ had no such illusion. He knew from the beginning that He came to be rejected and to die. And so He 'trod life's common way,' with that grim certainty rising ever before Him. I suppose that He did not, as you and I do, forget the death that awaits us, and find the non-remembrance of it the condition of much of our energy, but that it was perpetually in His sight.
Now I do not think that we sufficiently dwell upon that fact as an element in the human experience of our Lord. What beauty it gives to His gentleness, to the leisureliness of heart with which He was ready to make everybody's sorrow His own, and to lay a healing and a loving finger upon every wound! With this certainty before Him, there was yet no strain manifest upon His spirit, no self-absorption, no shutting Himself out from other people's burdens because He had so heavy ones of His own to carry; but He was ready for every joy, ready for all sympathy, ready for every help; and if we cannot say that, 'in cheerful godliness,' as I think we may, at least we can say that with solemn joy and untroubled readiness, He journeyed towards that Cross. This Isaac was under no illusions as to who the Lamb for the offering was, but knowing it, He patiently carried the wood and climbed the hill, ready for the Father's will.
II. That brings me to notice the second point here, our Lord's recognition of the necessity of His suffering.
Mark that He does not say that He _shall_ suffer. Certainty is not all that He proclaims here, however absolute that certainty might be, but it is '_He must_.' He is speaking not only of the historical fact, but of the need, deep in the nature of things, for His sufferings that were to follow.
And though these were wrought out by His own willing submission on the one hand, and by the unfettered play of the evil passions of the worst of men on the other, yet over all that apparent chaos of unbridled devildom there ruled the unalterable purpose of God; and the 'must' was wrought out through the passions of evil-doers and the voluntary submission of the innocent sufferer; thus setting before us, in the central fact of the history of humanity, viz. the Cross and passion of Jesus Christ, the eminent example of that great mystery how the absolute freedom of the human will, and the responsibility of the guilt of human wrong-doers, are congruous with the fixed purpose of an all-determining and all-ruling Providence.
