The combination is very remarkable. Like the eagle he rises, and like the eagle, with the impetus gained from his height, he drops right down on the earth beneath!
And that is not only a characteristic of St. John's teaching, but it is a characteristic of all the New Testament morality—its highest revelations are intensely practical. Its light is at once set to work, like the sunshine that comes ninety millions of miles in order to make the little daisies open their crimson-tipped petals; so the profoundest things that the Bible has to say are said to you and me, not that we may know only, but that knowing we may do, and do because we are.
So John, here: 'We shall be like Him, for we shall see Him as He is.' 'And'—a simple coupling-iron for two such thoughts—'every man that hath this hope in Him'—that is, in Christ, not in himself, as we sometimes read it—'every man that hath this hope,' founded on Christ, 'purifies himself even as He is pure.'
The thought is a very simple one, though sometimes it is somewhat mistakenly apprehended. Put into its general form it is just this:—If you expect, and expecting, hope to be like Jesus Christ yonder, you will be trying your best to be like Him here. It is not the mere purifying influence of hope that is talked about, but it is the specific influence of this one hope, the hope of ultimate assimilation to Christ leading to strenuous efforts, each a partial resemblance of Him, here and now. And that is the subject I want to say a word or two about now.
I. First, then, notice the principle that is here, which is the main thing to be insisted upon, namely, If we are to be pure, we must purify ourselves.
There are two ways of getting like Christ, spoken about in the context. One is the blessed way, that is more appropriate for the higher Heaven, the way of assimilation and transformation by beholding—'If we see Him' we shall be 'like Him.' That is the blessed method of the Heavens. Yes, but even here on earth it may to some extent be realised! Love always breeds likeness. And there is such a thing, here on earth and now, as gazing upon Christ with an intensity of affection, and simplicity of trust, and rapture of aspiration, and ardour of desire which shall transform us in some measure into His own likeness. John is an example of that for us. It was a true instinct that made the old painters always represent him as like the Master that he sat beside, even in face. Where did John get his style from? He got it by much meditating upon Christ's words. The disciple caught the method of the Master's speech, and to some extent the manner of the Master's vision.
And so he himself stands before us as an instance of the possibility, even on earth, of this calm, almost passive process, and most blessed and holiest method of getting like the Master, by simple gazing, which is the gaze of love and longing.
But, dear brethren, the law of our lives forbids that that should be the only way in which we grow like Christ. 'First the blade, then the ear, then the full corn in the ear,' was never meant to be the exhaustive, all-comprehensive statement of the method of Christian progress. You and I are not vegetables; and the Parable of the Seed is only one side of the truth about the method of Christian growth. The very word 'purify' speaks to us of another condition; it implies impurity, it implies a process which is more than contemplation, it implies the reversal of existing conditions, and not merely the growth upwards to unattained conditions.
And so growth is not all that Christian men need; they need excision, they need casting out of what is in them; they need change as well as growth. 'Purifying' they need because they are impure, and growth is only half the secret of Christian progress.
Then there is the other consideration, viz., if there is to be this purifying it must be done by myself. 'Ah!' you say, 'done by yourself? That is not evangelical teaching.' Well, let us see. Take two or three verses out of this Epistle which at first sight seem to be contradictory of this. Take the very first that bears on the subject:—'The blood of Jesus Christ His Son cleanseth us from all sin' (i. 7). 'If we confess our sins He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness' (i. 9). 'He that abideth in Him sinneth not' (iii. 6). 'This is the victory that overcometh the world, even our faith' (v. 4).
