So, then, two very plain practical principles may be deduced and enforced from this first thought. First, the purpose of all revelation and the test of all religion is—character and conduct.

It is all very well to know about God, to have our minds filled with true thoughts about Him, His nature, and dealings with us. Orthodoxy is good, but orthodoxy is a means to an end. There should be nothing in a man's creed which does not act upon his life. Or, if I may put it into technical words, all a man's credenda should be his agenda; and whatsoever he believes should come straight into his life to influence it, and to shape character. Here, then, is the warning against a mere notional orthodoxy, and against regarding Christian truth as being intended mainly to illuminate the understanding, or to be a subject of speculation and discussion. There are people in all generations, and there are plenty of them to-day, who seem to think that the great verities of the Gospel are mainly meant to provide material for controversy—

'As if religion were intended
For nothing else but to be mended';

and that they have done all that can be expected when they have tried to apprehend the true bearing of this revelation, and to contend against misinterpretations. This is the curse of religious controversy, that it blinds men to the practical importance of the truths for which they are fighting. It is as if one were to take some fertile wheat-land, and sand it all over, and roll it down, and make it smooth for a gymnasium, where nothing would grow. So the temper which finds in Christian truth simply a 'ministration of questions,' as my text says, mars its purpose, and robs itself of all the power and nourishment that it might find there.

No less to be guarded against is the other misconception which the clear grasp of our text would dismiss at once, that the great purpose for which God speaks to us men, in the revelation of Jesus Christ, is that we may, as we say, be 'forgiven,' and escape any of the temporal or eternal consequences of our wrongdoing. That is a purpose, no doubt, and men will never rise to the apprehension of the loftiest purposes, nor penetrate to a sympathetic perception of the inmost sweetness of the Gospel, unless they begin with its redemptive aspect, even in the narrowest sense of that word. But there are a miserable number of so-called and of real Christians in this world, and in our churches to-day, who have little conception that God has spoken to them for anything else than to deliver them from the fear of death, and from the incidence on them of future condemnation. He has spoken for this purpose, but the ultimate end of all is that we may be helped to love Him, and so to be like Him. The aim of the commandment is love, and if you ever are tempted to rest in intellectual apprehensions, or to pervert the truth of God into a mere arena on which you can display your skill of fence and your intellectual agility, or if ever you are tempted to think that all is done when the sweet message of forgiveness is sealed upon a man's heart, remember the solemn and plain words of my text—the final purpose of all is that we may love God and man.

But then, on the other side, note that no less distinctly is the sole foundation of this love laid in God's speech. My text, in its elevation of sentiment and character and conduct above doctrine, falls in with the prevailing tendencies of this day; but it provides the safeguards which these tendencies neglect. Notice that this favourite saying of the most advanced school of broad thinkers, who are always talking about the decay of dogma, and the unimportance of doctrine as compared with love, is here uttered by a man who was no sentimentalist, but to whom the Christian system was a most distinct and definite thing, bristling all over with the obnoxious doctrines which are by some of us so summarily dismissed as of no importance. My very text protests against the modern attempt to wrench away the sentiments and emotions produced in men, by the reception of Christian truth, from the truth which it recognises as the only basis on which they can be produced. It declares that the 'commandment' must come first, before love can follow; and the rest of the letter, although, as I say, it decisively places the end of revelation as being the moral and religious perfecting of men into assimilation with the divine love, no less decisively demands that for such a perfecting there shall be laid the foundation of the truth as it is revealed in Jesus Christ.

And that is what we want to-day in order to make breadth wholesome, and if only we will carry with us the two thoughts, the commandment and love, we shall not go far wrong. But what would you think of a man that said, 'I do not want any foundations. I want a house to live in'? And pray how are you going to get your house without the foundations? Or would he be a wise man who said, 'Oh, never mind about putting grapes into the vine vat, and producing fermentation; give me the wine!' Yes! But you must have the fermentation first. The process is not the result, of course, but there is no result without the process. And according to New Testament teaching, which, I am bold to say, is verified by experience, there is no deep, all-swaying, sovereign, heart-uniting love to God which is not drawn from the acceptance of the truth as it is in Jesus Christ.

II. And so I come, secondly, to note the purifying which is needed prior to such love.

Our text, as I said, divides the process into stages; or, if I may go back to a former illustration, into levels. And on the level immediately above the love, down into which the waters of the twin lakes glide, are a pure heart and a good conscience. These are the requisites for all real and operative love. Now they are closely connected, as it seems to me, more closely so than with either the stage which precedes or that which follows. They are, in fact, two twin thoughts, very closely identified, though not quite identical.

A pure heart is one that has been defecated and cleansed from the impurities which naturally attach to human affections. A 'good conscience' is one which is void of offence towards God and man, and registers the emotions of a pure heart. It is like a sheet of sensitive paper that, with a broken line, indicates how many hours of sunshine in the day there have been. We need not discuss the question as to which of these two great gifts and blessings which sweeten a whole life come first. In the initial stages of the Christian life I suppose the good conscience precedes the pure heart. For forgiveness which calms the conscience and purges it of the perilous stuff which has been injected into it by our corruptions—forgiveness comes before cleansing, and the conscience is calm before the heart is purified. But in the later stages of the Christian life the order seems to be reversed, and there cannot be in a man a conscience that is good unless there is a heart that is pure.
