I know thy works… – Revelation 3:8

I do not think that we should be so slow as we sometimes are in praising one another. There is a general theory abroad that it is quite right and proper to point out to a brother all his imperfections, for it will be a salutary medicine to him, and prevent his being too happy in this vale of tears. Is it supposed that we shall cheer him on to do better by always finding fault with him? If so, some people ought to be very good by this time, for they have had candid friends in plenty. Find fault with a brother and he will be kept from growing too proud; and he will, no doubt, go forward blessing you very much for your kind consideration in promoting his humility. Remember also that it is so much to the increase of brotherly love to have a clear eye to see the imperfections of our friends. Does anyone in his senses think so? I should suppose that after having given a sufficient trial to that manner of procedure, it would be quite as well at times to try another, and to rejoice in everything which we see of grace in our brethren, and sometimes to thank God in their hearing for what we perceive in them that we are sure is the fruit of the Spirit. If they are what they should be, they will not think so much of our little praises as to be unduly exalted thereby; but they will be sometimes so encouraged as to be nerved to higher and nobler things. If a man deserves my commendation, I am only paying a debt when I give it to him, and it is dishonest to withhold it under the pretense that he would not use the payment rightly. Men who deserve praise can bear it, and some of them even need it. I should not wonder that the kindly words of God’s people may be but a rehearsal of that “Well done, good and faithful servant” which will one day sound in their ears; and be a useful rehearsal, too, helping them on their weary way. Good men have many conflicts, let us minister to their comfort. At any rate, the great Head of the church did not think it unwise to say to the church at Philadelphia that He thought well of it because it had kept His word. Let us give honour to whom honour is due, and encourage those who are aiming to do right. ~ C.H. Spurgeon
