The Imitation of Christ, by Thomas a Kempis, tr. by William Benham , at sacred-texts.com
It is no hard thing to despise human comfort when divine is present. It is a great thing, yea very great, to be able to bear the loss both of human and divine comfort; and for the love of God willingly to bear exile of heart, and in nought to seek oneself, nor to look to one's own merit. What great matter is it, if thou be cheerful of heart and devout when favour cometh to thee? That is an hour wherein all rejoice. Pleasantly enough doth he ride whom the grace of God carrieth. And what marvel, if he feeleth no burden who is carried by the Almighty, and is led onwards by the Guide from on high?
2. We are willing to accept anything for comfort, and it is difficult for a man to be freed from himself. The holy martyr Laurence overcame the love of the world and even of his priestly master, because he despised everything in the world which seemed to be pleasant; and for the love of Christ he calmly suffered even God's chief priest, Sixtus, whom he dearly loved, to be taken from him. Thus by the love of the Creator he overcame the love of man, and instead of human comfort he chose rather God's good pleasure. So also learn thou to resign any near and beloved friend for the love of God. Nor take it amiss when thou hast been deserted by a friend, knowing that we must all be parted from one another at last.
3. Mightily and long must a man strive within himself before he learn altogether to overcome himself, and to draw his whole affection towards God. When a man resteth upon himself, he easily slippeth away unto human comforts. But a true lover of Christ, and a diligent seeker after virtue, falleth not back upon those comforts, nor seeketh such sweetness as may be tasted and handled, but desireth rather hard exercises, and to undertake severe labours for Christ.
4. When, therefore, spiritual comfort is given by God, receive it with giving of thanks, and know that it is the gift of God, not thy desert. Be not lifted up, rejoice not overmuch nor foolishly presume, but rather be more humble for the gift, more wary and more careful in all thy doings; for that hour will pass away, and temptation will follow. When comfort is taken from thee, do not straightway despair, but wait for the heavenly visitation with humility and patience, for God is able to give thee back greater favour and consolation. This is not new nor strange to those who have made trial of the way of God, for with the great saints and the ancient prophets there was often this manner of change.
5. Wherefore one said when the favour of God was present with him, I said in my prosperity I shall never be moved,(1) but he goeth on to say what he felt within himself when the favour departed: Thou didst turn Thy face from me, and I was troubled. In spite whereof he in no wise despaireth, but the more instantly entreateth God, and saith, Unto Thee, O Lord, will I cry, and will pray unto my God; and then he receiveth the fruit of his prayer, and testifieth how he hath been heard, saying, The Lord heard me and had mercy upon me, the Lord was my helper. But wherein? Thou hast turned my heaviness into joy, Thou hast put off my sackcloth and girded me with gladness. If it was thus with the great saints, we who are poor and needy ought not to despair if we are sometimes in the warmth and sometimes in the cold, for the Spirit cometh and goeth according to the good pleasure of His will. Wherefore holy Job saith, Thou dost visit him in the morning, and suddenly Thou dost prove him.(2)
6. Whereupon then can I hope, or wherein may I trust, save only in the great mercy of God, and the hope of heavenly grace? For whether good men are with me, godly brethren or faithful friends, whether holy books or beautiful discourses, whether sweet hymns and songs, all these help but little, and have but little savour when I am deserted by God's favour and left to mine own poverty. There is no better remedy, then, than patience and denial of self, and an abiding in the will of God.
7. I have never found any man so religious and godly, but that he felt sometimes a withdrawal of the divine favour, and lack of fervour. No saint was ever so filled with rapture, so enlightened, but that sooner or later he was tempted. For he is not worthy of the great vision of God, who, for God's sake, hath not been exercised by some temptation. For temptation is wont to go before as a sign of the comfort which shall follow, and heavenly comfort is promised to those who are proved by temptation. As it is written, To him that overcometh I will give to eat of the tree of life.(3)
8. Divine comfort is given that a man may be stronger to bear adversities. And temptation followeth, lest he be lifted up because of the benefit. The devil sleepeth not; thy flesh is not yet dead; therefore, cease thou not to make thyself ready unto the battle, for enemies stand on thy right hand and on thy left, and they are never at rest.
