Roman 14:1-23
Now accept the one who is weak in faith, but not for the purpose of passing judgment on his opinions.One person has faith that he may eat all things, but he who is weak eats vegetables only. The one who eats is not to regard with contempt the one who does not eat, and the one who does not eat is not to judge the one who eats, for God has accepted him. Who are you to judge the servant of another? To his own master he stands or falls; and he will stand, for the Lord is able to make him stand.

One person regards one day above another, another regards every day alike. Each person must be fully convinced in his own mind. He who observes the day, observes it for the Lord, and he who eats, does so for the Lord, for he gives thanks to God; and he who eats not, for the Lord he does not eat, and gives thanks to God. For not one of us lives for himself, and not one dies for himself; for if we live, we live for the Lord, or if we die, we die for the Lord; therefore whether we live or die, we are the Lord’s. For to this end Christ died and lived again, that He might be Lord both of the dead and of the living.

But you, why do you judge your brother? Or you again, why do you regard your brother with contempt? For we will all stand before the judgment seat of God.

For it is written, “AS I LIVE, SAYS THE LORD, EVERY KNEE SHALL BOW TO ME,AND EVERY TONGUE SHALL GIVE PRAISE TO GOD.”So then each one of us will give an account of himself to God.Therefore let us not judge one another anymore, but rather determine this—not to put an obstacle or a stumbling block in a brother’s way. I know and am convinced in the Lord Jesus that nothing is unclean in itself; but to him who thinks anything to be unclean, to him it is unclean. For if because of food your brother is hurt, you are no longer walking according to love. Do not destroy with your food him for whom Christ died.Therefore do not let what is for you a good thing be spoken of as evil; for the kingdom of God is not eating and drinking, but righteousness and peace and joy in the Holy Spirit. For he who in this way serves Christ is acceptable to God and approved by men. So then we pursue the things which make for peace and the building up of one another. Do not tear down the work of God for the sake of food. All things indeed are clean, but they are evil for the man who eats and gives offense. It is good not to eat meat or to drink wine, or to do anything by which your brother stumbles. The faith which you have, have as your own conviction before God. Happy is he who does not condemn himself in what he approves. But he who doubts is condemned if he eats, because his eating is not from faith; and whatever is not from faith is sin.

1 Corinthians 8:9,13
But take care that this liberty of yours does not somehow become a stumbling block to the weak.  For if someone sees you, who have knowledge, dining in an idol’s temple, will not his conscience, if he is weak, be strengthened to eat things sacrificed to idols?  For through your knowledge he who is weak is ruined, the brother for whose sake Christ died.  And so, by sinning against the brethren and wounding their conscience when it is weak, you sin against Christ.  Therefore, if food causes my brother to stumble, I will never eat meat again, so that I will not cause my brother to stumble.

Philippians 2:15
so that no one can criticize you. Live clean, innocent lives as children of God, shining like bright lights in a world full of crooked and perverse people.

Colossians 3:2, 5-10, 17
Set your mind on the things above, not on the things that are on earth.

Therefore consider the members of your earthly body as dead to immorality, impurity, passion, evil desire, and greed, which amounts to idolatry.  For it is because of these things that the wrath of God will come upon the sons of disobedience,  and in them you also once walked, when you were living in them. But now you also, put them all aside: anger, wrath, malice, slander, and abusive speech from your mouth. Do not lie to one another, since you laid aside the old self with its evil practices,  and have put on the new self who is being renewed to a true knowledge according to the image of the One who created him—

Whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks through Him to God the Father.
