4. Lastly, bodily injuries are a hindrance to delight. But contemplation is productive of bodily injuries, for we read in Genesis[396] that Jacob, after saying _I have seen God face to face, ... halted on his foot ... because He touched the sinew of his thigh and it shrank_. Whence it would seem that the contemplative life is not pleasurable. But after that contemplation Jacob halted on one foot because, as S. Gregory says, "it must needs be that as the love of this world grows weaker, so a man grows stronger in his love of God," and consequently, "when once we have known the sweetness of God, one of our feet remains sound while the other halts; for a man who halts with one foot leans only on the one that is sound."[397] "Tu esto nostrum gaudium Qui es futurus Praemium. Sit nostra in Te gloria Per cuncta semper saecula!" * * * * * _S. Gregory:_ Between the delights of the body and those of the heart there is ever this difference that the delights of the body are wont, when we have them not, to beget a keen yearning for them; but when we have them and eat our fill, they straightway beget disgust for them, for we are sated therewith. Spiritual joys, on the contrary, when we have them not are a weariness, but when we have them we desire them still more, and the more we feed upon them the more we hunger after them. In the case of the former, the yearning for them was a pleasure, trial of them brought disgust. In the case of the latter, in desire we held them cheap, trial of them proved a source of pleasure. For spiritual joys increase the soul's desire of them even while they sate us, for the more their savour is perceived, the more we know what it is we ought eagerly to love. Whence it comes to pass that when we have them not we cannot love them, for their savour is unknown to us. For how can a man love what he is ignorant of? Wherefore the Psalmist admonishes us, saying: _O taste and see that the Lord is sweet!_[398] As though he would say to us in plain terms: You know not His sweetness if ye have never tasted it; touch, then, the Food of Life with the palate of your soul that so, making proof of Its sweetness, ye may be able to love It. These joys man lost when he sinned in Paradise; he went out when he closed his mouth to the Food of Eternal Sweetness. Whence we too, who are born amidst the toils of this pilgrimage, come without relish to this Food; we know not what we ought to desire, and the sickness of our disgust grows the more the further our souls keep away from feeding upon that Sweetness; and less and less does our soul desire those interior joys the longer it has grown accustomed to do without them. We sicken, then, by reason of our very disgust, and we are wearied by the long-drawn sickness of our hunger (_Hom._ XXXVI., _On the Gospels_). VIII Is the Contemplative Life lasting?
