997. Its being 'given all to you' means enjoyment on account of use, which is 'for food', for whatever is given for food is for use. As regards use, the situation is this: People who are governed by charity, that is, who dwell in love towards the neighbour - from which love the living delight contained in pleasures derives - have no regard for the enjoyment of pleasures except on account of the use that is served; for charity does not exist if there are no works of charity. It is in the exercise of it, that is, in use, that charity consists. Someone who loves the neighbour as himself never experiences the delight of charity except in the exercise of it, or in use. Consequently the life of charity is a life of uses. Such life pervades the whole of heaven, for the Lord's kingdom, being a kingdom of mutual love, is a kingdom of uses. Every pleasure therefore that springs from charity finds its delight in use, and the more pre-eminent the use the greater the delight. For this reason it is the very being and nature of a use which determines the happiness that angels have from the Lord.
 The situation with every pleasure is that the more pre-eminent its use is, the greater is its delight. Take one example, the delight of conjugial love: since the seed-bed of human society derives from it, and from that seed-bed the Lord's kingdom in heaven, which constitutes the greatest use of all, it therefore contains, as has been stated, so much delight within itself as to constitute heavenly happiness. The same applies to all other pleasures, their differences depending on the excellence of their respective uses. Those uses are so many and various that they can scarcely be divided into genera and species. One use will relate more closely and directly to the Lord's kingdom, or the Lord, another more remotely and indirectly. From these considerations it is also clear that all pleasures are available to man, yet only for the sake of the use they serve; and thus though they vary according to the use they serve, they share in and receive their life from heavenly happiness.
