We cannot see all the grounds of that solemn imperative, but this we can see, that it was because of the requirements of the divine righteousness, and because of the necessities of sinful men. And so Christ's was no martyr's death, who had to die as the penalty of the faithful discharge of His duty. It was not the penalty that He paid for doing His work, but it was the work itself. Not that gracious life, nor 'the loveliness of perfect deeds,' nor His words of sweet wisdom, nor His acts of transcendent power, equalled only by the pity that moved the power, completed His task, but He 'came to give His life a ransom for many.'
'Must' is a hard word. It may express an unwelcome necessity. Was this necessity unwelcome? When He said, 'The Son of Man must be lifted up,' was He shrinking, or reluctantly submitting? Ah, no! He _must_ die because He _would_ save, and He _would_ save because He _did_ love. His filial obedience to God coincided with His pity for men: and not merely in obedience to the requirements of the divine righteousness, but in compassion for the necessities of sinners, necessity was laid upon Him.
Oh, brethren! nothing held Christ to the Cross but His own desire to save us. Neither priests nor Romans carried Him thither. What fastened Him to it was not the nails driven by rude hands. And the reason why He did not, as the taunters bade Him do, come down from it, was neither a physical nor a moral necessity unwelcome to Himself, but the yielding of His own will to do all which was needed for man's salvation.
This sacrifice was bound to the altar by the cords of love. We have heard of martyrs who have refused to be tied to the stake, and have kept themselves motionless in the centre of the fierce flames by the force of their wills. Jesus Christ fastened Himself to the Cross and died because He would.
And, oh! if we think of that sweet, serene life as having clear before it from the very first steps that grim end, how infinitely it gains in pathetic beauty and in heart-touchingness! What wonderful self-abnegation! How he was at leisure from Himself, with a heart of pity for every sorrow, and loins girt for all service, though during all His life the Cross closed the vista! Think that human shrinking was felt by Him, think that it was so held back that His purpose never faltered, think that each of us may say, 'He _must_ die because He _would_ save me'; and then ask, 'What shall I render to the Lord for all His benefits toward me?'
II. In a second class of these utterances, we see Christ impelled by filial obedience and the consciousness of His mission.
'Wist ye not that I must be about My Father's business?' That was a strange utterance for a boy of twelve. It seems to negative the supposition that what is called the 'Messianic consciousness' dawned upon Jesus Christ first after His baptism and the descent of the Spirit. But however that may be, it and the similar passages to which I have already referred, bearing upon His discharge of His work prior to His death, teach that the necessity was an inward necessity springing from His consciousness of Sonship, and His recognition of the work that He had to do. And so He is our great Example of spontaneous obedience, which does violence to itself if it does not obey. It was instinct that sent the boy into the Temple. Where should a Son be but in His Father's house? How could He not be doing His Father's business?
Thus He stands before us, the pattern for the only obedience that is worth calling so, the obedience which would be pained and ill at ease unless it were doing the work of God. Religion is meant to make it a second nature, or, as I have ventured to call it, an instinct—a spontaneous, uncalculating, irrepressible desire—to be in fellowship with God, and to be doing His will. That is the meaning of our Christianity. There is no obedience in reluctant obedience; forced service is slavery, not service. Christianity is given for the specific purpose that it may bring us so into touch with Jesus Christ as that the mind which was in Him may be in us; and that we too may be able to say, with a kind of wonder that people should have expected to find us in any other place, or doing anything else, 'Wist ye not that because I am a Son, _I_ must be about my Father's business?' As certainly as the sunflower follows the sun, so certainly will a man animated by the mind that was in Jesus Christ, like Him find his very life's breath in doing the Father's will.
