1But the Spirit says expressly that in later times some will fall away from the faith, paying attention to seducing spirits and doctrines of demons, 2through the hypocrisy of men who speak lies, branded in their own conscience as with a hot iron, 3forbidding marriage and commanding to abstain from foods which God created to be received with thanksgiving by those who believe and know the truth. 4For every creature of God is good, and nothing is to be rejected if it is received with thanksgiving. 5For it is sanctified through the word of God and prayer.
6If you instruct the brothers of these things, you will be a good servant of Christ Jesus, nourished in the words of the faith and of the good doctrine which you have followed. 7But refuse profane and old wives’ fables. Exercise yourself toward godliness. 8For bodily exercise has some value, but godliness has value in all things, having the promise of the life which is now and of that which is to come. 9This saying is faithful and worthy of all acceptance. 10For to this end we both labor and suffer reproach, because we have set our trust in the living God, who is the Savior of all men, especially of those who believe. 11Command and teach these things.
12Let no man despise your youth; but be an example to those who believe, in word, in your way of life, in love, in spirit, in faith, and in purity. 13Until I come, pay attention to reading, to exhortation, and to teaching. 14Don’t neglect the gift that is in you, which was given to you by prophecy with the laying on of the hands of the elders. 15Be diligent in these things. Give yourself wholly to them, that your progress may be revealed to all. 16Pay attention to yourself and to your teaching. Continue in these things, for in doing this you will save both yourself and those who hear you.
The holiness of Yahweh is evident in the unique practices within Israel and in the role of the Levitical System. "Speak to the children of Israel, and say to them, 'When a man consecrates a person to Yahweh in a vow."
The Levitical laws demonstrate the holiness of God. The Lord is perfect and pure and so requires the perfection of sacrifice before we can enjoy His presence forever (Genesis 3:21; Deuteronomy 32:3-4; Psalms 16:10-11; 40:6-8; 49:7-9; Hebrews 10:1-18). Because sinners are alienated from God’s holiness, the offering of the blood of the sacrifice satisfies the wrath of God against sinners (Romans 3:9-31; 5:6-11). The ritual laws required the shedding of blood for the forgiveness of sins, that is, to make atonement for souls (Leviticus 17:10-11, 14). The blood of animals was used as a type or symbol of the blood of Christ until Christ actually came to shed His own blood for our sins (Exodus 25:9, 40; 26:30; 27:8; Numbers 8:4; 1 Chronicles 28:9-19; Romans 3:25; Acts 14:16; 17:30-31; Hebrews 8:5; 9:6-10, 23-25; 10:1-18). The dietary laws made a distinction between clean and unclean animals, also to remind the people of the holiness of God (Leviticus 11:1-47; Deuteronomy 14:1-21). God is unique and distinct, and so the people who belong to Him were to be the same among all the peoples of the earth (Leviticus 11:44-45; Deuteronomy 4:1-8; 7:6-11). God is holy; therefore, His people were to be holy (Leviticus 11:44). Now that Jesus Christ has come, the following passages have a bearing on this issue: Mark 7:19; Acts 10:1-11:14; 15:1-29; Colossians 2:16-23; and 1 Timothy 4:1-5. The moral laws of the Ten Commandments (Exodus 20:1-17; Deuteronomy 5:6-21) or the detailed moral statutes found elsewhere (Exodus 21-23; Leviticus 18 and 20) also demonstrated the holiness of God as opposed to the sinfulness of man. For example, the one who practices sexual immorality defiles himself and violates God’s holiness. The Lord said, “Do not defile yourselves by any of these things; for by all these the nations which I am casting out before you have become defiled (Leviticus 18:24),” and, “Thus you are to be holy to Me, for I the LORD am holy; and I have set you apart from the peoples to be Mine (Leviticus 20:26).” The apostle made the same connection by saying, “Flee immorality…glorify God in your body (1 Corinthians 6:18-20),” “if a man cleanses himself from these things, he will be a vessel for honor, sanctified, useful to the Master (2 Timothy 2:19-22).” Submission to God’s moral law is so vital that when disobedience is the practice, the Scripture says, “I forewarn you just as I have forewarned you that those who practice such things shall not inherit the kingdom of God (Galatians 5:21).” See also Romans 7:1-6; 13:14; 1 Corinthians 3:16-17; 6:9-11; Galatians 5:16-24; Ephesians 5:1-13; Colossians 3:5-11; Titus 2:11-14; Hebrews 13:4; 1 Peter 4:3; 2 Peter 2; and Jude 4.
