It is not what you are nor what you have been that God sees with all-merciful eyes, but what you desire to be. - The Cloud of UnknowingOr, in context:
Sometimes it is withdrawn for their carelessness; and when it is thus, they feel soon after a full bitter pain that beateth them full sore. Sometimes our Lord will delay it by an artful device, for He will by such a delaying make it grow, and be had more in dainty when it is new found and felt again that long had been lost. And this is one of the readiest and sovereignest tokens that a soul may have to wit by, whether he be called or not to work in this work, if he feel after such a delaying and a long lacking of this work, that when it cometh suddenly as it doth, unpurchased with any means, that he hath then a greater fervour of desire and greater love longing to work in this work, than ever he had any before. Insomuch, that ofttimes I trow, he hath more joy of the finding thereof than ever he had sorrow of the losing.
And if it be thus, surely it is a very token without error, that he is called of God to work in this work, whatsoever that he be or hath been. For not what thou art, nor what thou hast been, beholdeth God with His merciful eyes; but that thou wouldest be. And Saint Gregory to witness, that all holy desires grow by delays: and if they wane by delays, then were they never holy desires. For he that feeleth ever less joy and less, in new findings and sudden presentations of his old purposed desires, although they may be called natural desires to the good, nevertheless holy desires were they never. Of this holy desire speaketh Saint Austin and saith, that all the life of a good Christian man is nought else but holy desire.
