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. So then, brethren, what about our grudging service? What about our reluctant obedience? What about the widespread mistake that religion prohibits wished-for things and enforces unwelcome duties? If my Christianity does not make me recoil from what it forbids, and spring eagerly to what it commends, my Christianity is of very little use. If when in the Temple we are like idle boys in school, always casting glances at the clock and the door, and wishing ourselves outside, we may just as well be out as in. Glad obedience is true obedience. Only he who can say, 'Thy law is within my heart, and I do Thy will because I love Thee, and cannot but do as Thou desirest,' has found the joy possible to a Christian life. It is not 'harsh and crabbed,' as those that look upon it from the outside may 'suppose,' but musical and full of sweetness. There is nothing more blessed than when 'I choose' covers exactly the same ground as 'I ought.' And when duty is delight, delight will never become disgust, nor joy pass away. III. We see, in yet another use of this great 'must,' Christ anticipating His future triumph. 'Other sheep I have which are not of this fold; them also I must bring, and there shall be one flock and one Shepherd.' Striking as these words are in themselves, they are still more striking when we notice their connection; for they follow immediately upon His utterance about laying down His life for the sheep. So, then, this was a work beyond the Cross, and whatever it was, it was to be done after He had died.
