According as He hath chosen us in Him before the foundation of the world, that we should be holy and without blame before Him in love. – Ephesians 1:4

What the world expects in Christians is real holiness as well as consistency. Holiness is something more than virtue. Virtue is like goodness frozen into ice, hard and cold; but holiness is that same goodness when it is thawed into a clear, running, sparkling stream. Virtue is the best thing that philosophy can produce, but holiness is the true fruit of the gospel of Jesus Christ, and of that alone. There must be about us an unworldliness, a something out of the common and ordinary way, or else, mark you, that uncommon gospel, that heavenly gospel, which we hold, will not seem to be bringing forth its legitimate fruit. If you are just barely honest, and no more, if you are barely moral, and no more, it is of no service that you should try to speak of Christ; the world will not reckon you as the fairest among women, and it will not enquire anything about your Well-beloved.

We do hope that we have something Christ-like about us; but oh, how little it is! How many imperfections there are! How much is there of the old Adam, and how little of the new creature in Christ Jesus!…We want more grace. It is to be had; and if we had it, and it transformed us into what we should be, oh, what lives of happiness and of holiness we might lead here below, and what mighty workers should we be for our Lord Jesus Christ! How would His dear name be made to sound to the utmost ends of the earth! I fear it is but a dream; but just conceive that all of you, the members of this church, were made to be truly saintly, saints of the first water, saints who had cast off the sloth of worldliness, and had come out in the full glory of newness of life in Christ Jesus, oh, what a power might this church become in London, and what a power to be felt the wide world over! Let us seek it, let us strive after it, recollecting that it is a truth never to be denied that only in proportion to the sanctity and spirituality of our character will be our influence for good amongst the sons of men. ~ C.H. Spurgeon
