1. No practical discriminations or determinations are of any worth in God's sight except as they are animated by love, and, indeed, determined by it. If a Christian should choose anything, or reject anything, yet not in love, his choice as to the matter of fact may be right, but for all that the man himself is wrong.
2. Love alone will practically carry through such habitual discrimination, such faithful and patient choice. Love becomes the new instinct which gives life, spring, and promptitude to the process. When this fails, the life of approving the things that are more excellent will fail; the task will be repudiated as a burden that cannot be endured. It may still be professed, but it must inwardly die.
3. Nothing but love can enable us to see and to affirm the true distinctions. Under the influence of that pure love (that arises in the heart which God's love has won and quickened) the things which differ are truly seen. So, and only so, we shall make distinctions according to the real differences as these appear in God's sight. Let us consider this a little.
Evidently among the things that differ there are some whose characteristics are so plainly written in conscience or in Scripture, that to determine what should be said of them is matter of no difficulty at all. It is no matter of difficulty to decide that murder and theft are wrong, or that meekness, benevolence, justice are right. A man who has never been awakened to spiritual life, or a Christian whose love has decayed, can make determinations about such things, and can be sure, as he does so, that as to the thing itself he is judging right. Yet in this case there is no just apprehension of the real difference in God's sight of the things that differ, nor a right mind and heart to choose or to reject so as to be in harmony with God's judgment.
And if so, then in that large class of cases where there is room for some degree of doubt or diversity, where some mist obscures the view, so that it is not plain at once into what class things should be reckoned—in cases where we are not driven to a decision by a blaze of light from Scripture or conscience—in such cases we need the impulse of the love which cleaves to God, which delights in righteousness, which gives to others, even to the undeserving, the brother's place in the heart. Without this there can be no detection of the real difference, and no assurance of the rectitude of the discrimination we make.
Now it is in such matters that the especial proof and exercise of religious life goes on. Here, for example, Lot failed. The beauty of the fair and prosperous valley so filled his soul with admiration and desire, that it chilled and all but killed the affections that should have steadied and raised his mind. Had the love of the eternal and supreme maintained its power, then in that day when God on the one hand and Lot on the other looked down on the plain, they would have seen the same sight and judged it with the same mind. But it was otherwise. So the Lord lifted up His eyes and saw that the men of Sodom were wicked and sinners before the Lord exceedingly; and Lot lifted up his eyes and saw only that the plain was well watered everywhere, as the garden of the Lord, as the land of Egypt.
But the love of which the Apostle speaks is the breath of the upper world and of the new life. It cleaves to God, it embraces the things which God loves, it enters into the views which God reveals,—and it takes the right view of men, and of men's interest and welfare. The man that has it, or has known it, is therein aware of what is most material. He has a notion of the conduct that is congruous to love's nature. What love knows, it is the nature of love to practise, for it knows lovingly; and at every step the practice confirms, establishes, and enlarges the knowledge. So the genuine growth of love is a growth in knowledge (ver. 9)—the word implies the kind of knowledge that goes with intently looking into things: love, as it grows, becomes more quick to see and mark how things really are when tried by the true standard. Conversing practically with the mind of God in the practice of life, love incorporates that mind and judges in the light of it. This prepares a man to detect the false and counterfeit, and to try the things that differ.
Not only in knowledge shall love grow, but "in all discernment," or perception, as it might be rendered. There may be instances in which, with our best wisdom, we find it hard to disentangle clear principles, or state plain grounds which rule the case; yet love, growing and exercised, has its percipiency: it has that accomplished tact, that quick experienced taste, that fine sensibility to what befriends and what opposes truth and right, which will lead to right distinctions in practice. So you discriminate by the sense of taste things that differ, though you can give no reason to another, but can only say, "I perceive it." In this sense "he that is spiritual judgeth all things."
For all this the aid of the Holy Spirit is held out to us, as we may see in 1 John ii. He makes love to grow, and under that master influence unfolds the needed wisdom also. So comes the wisdom "from above, which is first pure, then peaceable, gentle, and easy to be entreated, full of mercy and of good fruits, without partiality and without hypocrisy" (James iii. 17). It is hidden from many wise and prudent, but God has often revealed it unto babes.
