In the Old Testament the people were told what they could or could not eat. You can find it in Leviticus chapter 11 & Deuteronomy chapter 14. There were a lot of rules.
That was the first Covenant. Jesus brought in a better Covenant.
And this is what He said:
Matthew 6:25 Therefore I say unto you, Take no thought for your life, what ye shall eat, or what ye shall drink; nor yet for your body, what ye shall put on. Is not the life more than meat, and the body than raiment?
Matthew 6:31 Therefore take no thought, saying, What shall we eat? or, What shall we drink? or, Wherewithal shall we be clothed?
Luke 12:22 And he said unto his disciples, Therefore I say unto you, Take no thought for your life, what ye shall eat; neither for the body, what ye shall put on.
Luke 12:29 And seek not ye what ye shall eat, or what ye shall drink, neither be ye of doubtful mind.
Thought: Strong's #3309: To be anxious - to be troubled with cares.
Seek: Strong's #2212: To seek [in order to find out] by thinking, meditating, reasoning, to enquire into.
Jesus said, "Take no thought about what you eat or drink."
Paul told Timothy that nothing we eat should be refused if it is received with thanksgiving. It is purified by the Word & prayer.
1 Timothy 4:1 Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;
1 ti 4:2 Speaking lies in hypocrisy; having their conscience seared with a hot iron;
1 ti 4:3 Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth.
1 ti 4:4 For every creature of God is good, and nothing to be refused, if it be received with thanksgiving:
1 ti 4:5 For it is sanctified by the word of God and prayer.
When Jesus sent His disciples out this is what He told them:
Luke 10:7 And in the same house remain, eating and drinking such things as they give: for the labourer is worthy of his hire. Go not from house to house.
Lu 10:8 And into whatsoever city ye enter, and they receive you, eat such things as are set before you.
Jesus said that what goes into a man's belly does not defile him (make him unclean).
Mark 7:18 And he saith unto them, Are ye so without understanding also? Do ye not perceive, that whatsoever thing from without entereth into the man, it cannot defile him;
Mr 7:19 Because it entereth not into his heart, but into the belly, and goeth out into the draught, purging all meats?
Mr 7:20 And he said, That which cometh out of the man, that defileth the man.
Mr 7:21 For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders,
Mr 7:22 Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness:
Mr 7:23 All these evil things come from within, and defile the man.
Paul told the Gentiles not to eat food offered to idols, not to eat blood, and things strangled.
Acts 15:28 For it seemed good to the Holy Ghost, and to us, to lay upon you no greater burden than these necessary things;
Ac 15:29 That ye abstain from meats offered to idols, and from blood, and from things strangled, and from fornication: from which if ye keep yourselves, ye shall do well. Fare ye well.
1 Corinthians 8:4 As concerning therefore the eating of those things that are offered in sacrifice unto idols, we know that an idol is nothing in the world, and that there is none other God but one.
1co 8:5 For though there be that are called gods, whether in heaven or in earth, (as there be gods many, and lords many,)
1co 8:6 But to us there is but one God, the Father, of whom are all things, and we in him; and one Lord Jesus Christ, by whom are all things, and we by him.
1co 8:7 Howbeit there is not in every man that knowledge: for some with conscience of the idol unto this hour eat it as a thing offered unto an idol; and their conscience being weak is defiled.
1co 8:8 But meat commendeth us not to God: for neither, if we eat, are we the better; neither, if we eat not, are we the worse.
1co 8:9 But take heed lest by any means this liberty of yours become a stumblingblock to them that are weak.
1co 8:10 For if any man see thee which hast knowledge sit at meat in the idol's temple, shall not the conscience of him which is weak be emboldened to eat those things which are offered to idols;
1co 8:11 And through thy knowledge shall the weak brother perish, for whom Christ died?
1co 8:12 But when ye sin so against the brethren, and wound their weak conscience, ye sin against Christ.
1co 8:13 Wherefore, if meat make my brother to offend, I will eat no flesh while the world standeth, lest I make my brother to offend.
We are not to argue about what we do or do not eat. Each one is to do what is best for him or her. Don't cause a brother or sister to stumble with your eating.
Romans 14:1 Him that is weak in the faith receive ye, but not to doubtful disputations.
Ro 14:2 For one believeth that he may eat all things: another, who is weak, eateth herbs.
Ro 14:3 Let not him that eateth despise him that eateth not; and let not him which eateth not judge him that eateth: for God hath received him.
Romans 14:14 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.
Ro 14:15 But if thy brother be grieved with thy meat, now walkest thou not charitably. Destroy not him with thy meat, for whom Christ died.
Ro 14:16 Let not then your good be evil spoken of:
Ro 14:17 For the kingdom of God is not meat and drink; but righteousness, and peace, and joy in the Holy Ghost.
Romans 14:20 For meat destroy not the work of God. All things indeed are pure; but it is evil for that man who eateth with offence.
Ro 14:21 It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak.
Ro 14:22 Hast thou faith? have it to thyself before God. Happy is he that condemneth not himself in that thing which he alloweth. Ro 14:23 And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith is sin.
Paul said this in 1 Corinthians 6:12 All things are lawful unto me, but all things are not expedient: all things are lawful for me, but I will not be brought under the power of any.
Here's how the Amplified Bible reads: I Corinthians 6:12 Everything is permissible (allowable and lawful) for me; but not all things are helpful (good for me to do, expedient and profitable when considered with other things). Everything is lawful for me, but I will not become the slave of anything or be brought under its power.
Colossians 2:16 Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days:
Col 2:17 Which are a shadow of things to come; but the body is of Christ.
Proverbs 23:21 For the drunkard and the glutton shall come to poverty: and drowsiness shall clothe a man with rags.
New Century Version:
Proverbs 23:21 Those who drink and eat too much become poor.
They sleep too much and end up wearing rags.
In 2 Peter 1:5-7 Peter tells us to add to our faith temperance which is self-control. Timothy also says in 2 Timothy 3:1-9 that in the last days men will have no self-control.
The ability to say “no” to anything in excess—self-control—is one of the fruits of the Spirit common to all believers (Galatians 5:22).
We are not to let our appetites control us, but we are to have control over our appetites.
Paul said in 1 Corinthians 9:27 But I keep under my body, and bring it into subjection. He is saying that he makes his body do what he wants it to do by discipline.
If we are unable to control our eating habits, we are probably also unable to control other habits.
Philippians 4:5 Let your moderation be known unto all men. The Lord is at hand.
Php 4:6 Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.
Php 4:7 And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.
