1 Corinthians 6:13

Meats for the belly, and the belly for meats This is a matter of comparatively trifling importance. Meat is a necessity for our present undeveloped life; in the world where hunger and thirst will be no more it will no longer be so. And therefore both it, and the organs formed to digest it will be no longer wanted.

Now the body is not for fornication St Paul is led, by the importance he attaches to this point, to treat it first. The abominable licentiousness of heathen cities in general, and of Corinth in particular (see Dean Stanley's note on 1 Corinthians 6:12) had led to a general conviction that the body wasfor fornication. St Paul contradicts this, and most emphatically proclaims that what was always permitted among heathens, and even in some cases enjoined as a religious rite, was distinctly in itself an unlawful act, not excusable on the plea of necessity, which he had admitted in the case of meats, nor, like them, a question of "nicely calculated less or more," but contrary to the laws laid down by God for man, and calculated to deprive men of the blessings of the Resurrection.

but for the Lord i.e. Jesus Christ. The body is not formed to serve a purely material end, but is the instrument of the spirit, and its end the glory of God, through Christ.

and the Lord for the body Because from our point of view Christ came that we might serve and honour Him in our bodies. This sentence answers to -meats for the belly, and the belly for meats," above.
