Romans chapter 14

For one believeth that he may eat all things: another, who is weak, eateth herbs.

Who art thou that judgest another man's servant? to his own master he standeth or falleth. Yea, he shall be holden up: for God is able to make him stand.

He that regardeth the day, regardeth it unto the Lord; and he that regardeth not the day, to the Lord he doth not regard it. He that eateth, eateth to the Lord, for he giveth God thanks; and he that eateth not, to the Lord he eateth not, and giveth God thanks.

For whether we live, we live unto the Lord; and whether we die, we die unto the Lord: whether we live therefore, or die, we are the Lord's.

But why dost thou judge thy brother? or why dost thou set at nought thy brother? for we shall all stand before the judgment seat of Christ.

So then every one of us shall give account of himself to God.

I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself: but to him that esteemeth any thing to be unclean, to him it is unclean.

Let not then your good be evil spoken of:

For he that in these things serveth Christ is acceptable to God, and approved of men.

For meat destroy not the work of God. All things indeed are pure; but it is evil for that man who eateth with offence.

Hast thou faith? have it to thyself before God. Happy is he that condemneth not himself in that thing which he alloweth.
