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.
I need not point out to you how far afield Christ's vision goes out into the dim, waste places, where on the dark mountains the straying sheep are torn and frightened and starving. I need not dwell upon how far ahead in the future His glance travels, or how magnificent and how rebuking to our petty narrowness this great word is. 'There shall be one _flock_' (not fold); and they shall be one, not because they are within the bounds of any visible 'fold,' but because they are gathered round the one Shepherd, and in their common relation to Him are knit together in unity.
But what sort of a Man is this who considers that His widest work is to be done by Him after He is dead? 'Them also I _must_ bring.' Thou? how? when? Surely such words as these, side by side with a clear prevision of the death that was so soon to come, are either meaningless or the utterance of an arrogance bordering on insanity, or they anticipate what an Evangelist declares did take place—that the Lord was 'taken up into heaven and sat at the right hand of God,' whilst His servants 'went everywhere preaching the Word, the Lord also working with them and confirming the Word' with the signs He wrought.
'Them also I must bring.' That is not merely a necessity rooted in the nature of God and the wants of men. It is not merely a necessity springing from Christ's filial obedience and sense of a mission; but it is a 'must' of destiny, a 'must' which recognises the sure results of His passion; a 'must' which implies the power of the Cross to be the reconciliation of the world. And so for all pessimistic thoughts to-day, or at any time, and when Christian men's hearts may be trembling for the Ark of God—although, perhaps, there may be little reason for the tremor—and in the face of all blatant antagonisms and of proud Goliaths despising the 'foolishness of preaching,' we fall back upon Christ's great 'must.' It is written in the councils of Heaven more unchangeably than the heavens; it is guaranteed by the power of the Cross; it is certain, by the eternal life of the crucified Saviour, that He will one day be the King of humanity, and _must_ bring His wandering sheep to couch in peace, one flock round one Shepherd.
