1 Corinthians 10:25,26

'Whatever is sold in the shambles (meat market), eat, asking no question for conscience' sake, for the earth is the Lord's, and its fullness.'

But having forbidden the eating of sacrificial meat in temples he now turns to the question of meat sold externally by temples to the meat markets, some of which might also have been sacrificed to idols. Must this then also be avoided in case it had been sacrificed to idols? Pious Jews were in fact expected to ask whether such meat had been sacrificed to idols, and if it had not to eat it. After Paul's previous words pious Christians might have felt that they should do the same. But Paul points out that for Christians whether Jew or non-Jew it is unnecessary. Meat itself does not become contaminated by religious use, it is known connection with such use that disqualifies it, because of the weaker consciences of others. Otherwise it can be eaten with alacrity.

The reference here is to meat bought in the meat market whose origin is unknown. In that case, he says, they may eat of it without asking questions, for being of unknown origin it is neither giving a false witness to others, nor is it in any way giving countenance to idols. For everything that is in the world is God's for Him to dispose of as He will and idols and demons cannot affect meat. It is only when there is a conscious connection with idol worship that such meat has to be avoided, simply because of the bad effect such eating may have on some people. So what he has previously said does not mean that they must question the origin of every piece of meat they come across. Let them express their loyalty to the Creator by eating of it secure in the knowledge that it is His provision, part of what He has given man in creation, and that none other supposed creators matter.

'For the earth is the Lord's, and its fullness (what is in it).' This phrase from Psalms 24:1 was regularly used in grace at Jewish tables. Thus we may well see Paul as saying, 'having given thanks for it you may certainly eat of it if no reason is given why you should not'. For it is all part of God's provision.
