1Brothers, I couldn’t speak to you as to spiritual, but as to fleshly, as to babies in Christ. 2I fed you with milk, not with solid food, for you weren’t yet ready. Indeed, you aren’t ready even now, 3for you are still fleshly. For insofar as there is jealousy, strife, and factions among you, aren’t you fleshly, and don’t you walk in the ways of men? 4For when one says, “I follow Paul,” and another, “I follow Apollos,” aren’t you fleshly?
5Who then is Apollos, and who is Paul, but servants through whom you believed, and each as the Lord gave to him? 6I planted. Apollos watered. But God gave the increase. 7So then neither he who plants is anything, nor he who waters, but God who gives the increase. 8Now he who plants and he who waters are the same, but each will receive his own reward according to his own labor. 9For we are God’s fellow workers. You are God’s farming, God’s building.
10According to the grace of God which was given to me, as a wise master builder I laid a foundation, and another builds on it. But let each man be careful how he builds on it. 11For no one can lay any other foundation than that which has been laid, which is Jesus Christ. 12But if anyone builds on the foundation with gold, silver, costly stones, wood, hay, or straw, 13each man’s work will be revealed. For the Day will declare it, because it is revealed in fire; and the fire itself will test what sort of work each man’s work is. 14If any man’s work remains which he built on it, he will receive a reward. 15If any man’s work is burned, he will suffer loss, but he himself will be saved, but as through fire.
16Don’t you know that you are God’s temple and that God’s Spirit lives in you? 17If anyone destroys God’s temple, God will destroy him; for God’s temple is holy, which you are.
18Let no one deceive himself. If anyone thinks that he is wise among you in this world, let him become a fool that he may become wise. 19For the wisdom of this world is foolishness with God. For it is written, “He has taken the wise in their craftiness.” 20And again, “The Lord knows the reasoning of the wise, that it is worthless.” 21Therefore let no one boast in men. For all things are yours, 22whether Paul, or Apollos, or Cephas, or the world, or life, or death, or things present, or things to come. All are yours, 23and you are Christ’s, and Christ is God’s.
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.
