1 Corinthians 10:31 - Matthew Poole's English Annotations on the Holy Bible

The apostle, in these three last verses, layeth down three rules, to direct Christians how to use their liberty as to things that are of an indifferent nature, neither in themselves commanded nor forbidden in the word of God. His first rule is in this verse, to do whatsoever we do to the glory of God. This is a general rule, not to be restrained to the eating of meat offered to idols, of which the former discourse had been. It is a general rule, not applicable alone to eating and drinking, but to all other human actions. The reasonableness of this rule appeareth from our consideration, that the glory of God was the end of our creation; The Lord hath made all things for himself, Proverbs 16:4: and indeed it is impossible it should be otherwise; for whereas every reasonable agent both propounds to himself some end of his actions, and the best end he can imagine, it is impossible but that God also, in creating man, should propound to himself some end, and there being no better end than his own glory, he could propound no other unto himself. The glory of God being the end which he propounded to himself in creating man, it must needs follow, that that must be the chief and greatest end which any man can propound to himself in his actions. God is then glorified by us, when by our means, or by occasion of us, he is well spoken of in the world, or by our obedience to his will: this our Saviour hath taught us, 1 Thessalonians 17:4,6. No man in any of his actions hath a liberty from this rule; so as though a man, as to many things, hath a liberty to marry or not to marry, to eat meats or not to eat them, to wear this apparel or not to wear it; yet he is not even in such things as these so at liberty, but he ought to look about, and to consider circumstances, which will be most for the honour of God, the credit of the gospel, and reputation of religion. And the judgment of this is to be made from circumstances, the difference of which may make that unlawful which otherwise would be lawful, and that lawful which under other circumstances would be unlawful.
