God sets apart what is holy—He defines what is acceptable and righteous, not man. We must strictly avoid anything that would contaminate us, either physically or spiritually. Deuteronomy 14:2; For thou art a holy people unto the LORD thy God, and the LORD hath chosen thee to be His own treasure out of all peoples that are upon the face of the earth. 1 Corinthians 6:15-20. Do you not know that your bodies are members of Christ himself? Shall I then take the members of Christ and unite them with a prostitute? Do you not know that he who unites himself with a prostitute is one with her in body? For it is said, “The two will become one flesh.”[a] 17 But whoever is united with the Lord is one with him in spirit. Ceremonial law was a part of everyday life for the ancient Israelites, a way to teach them the spiritual principles needed to keep the law.
God then tells His people that they are to be holy ( 1 Peter 1:16). For it is written: “Be holy, because I am holy.” Spiritual discernment and heart are to learn these laws (1 Corinthians 2:14). Therefore God altered His approach, not because of flaws in the law, but because of the people. The person without the Spirit does not accept the things that come from the Spirit of God but considers them foolishness, and cannot understand them because they are discerned only through the Spirit.
We do not have a nation ruled by God’s law which are holy (Leviticus 20:26.) You are to be holy to me because I, the Lord, am holy, and I have set you apart from the nations to be my own and blessed (Deuteronomy 28:1-14), but only if they had a heart of obedience. Blessings for Obedience. If you fully obey the Lord your God and carefully follow all his commands I give you today, the Lord your God will set you high above all the nations on earth. All these blessings will come on you and accompany you if you obey the Lord your God: You will be blessed in the city and blessed in the country. The fruit of your womb will be blessed, and the crops of your land and the young of your livestock—the calves of your herds and the lambs of your flocks. Your basket and your kneading trough will be blessed. You will be blessed when you come in and blessed when you go out. The Lord will grant that the enemies who rise up against you will be defeated before you. They will come at you from one direction but flee from you in seven. The Lord will send a blessing on your barns and on everything you put your hand to. The Lord your God will bless you in the land he is giving you. The Lord will establish you as his holy people, as he promised you on oath, if you keep the commands of the Lord your God and walk in obedience to him. Then all the peoples on earth will see that you are called by the name of theLord, and they will fear you. The Lord will grant you abundant prosperity—in the fruit of your womb, the young of your livestock and the crops of your ground—in the land he swore to your ancestors to give you. The Lord will open the heavens, the storehouse of his bounty, to send rain on your land in season and to bless all the work of your hands. You will lend to many nations but will borrow from none. The Lord will make you the head, not the tail. If you pay attention to the commands of the Lord your God that I give you this day and carefully follow them, you will always be at the top, never at the bottom. Do not turn aside from any of the commands I give you today, to the right or to the left, following other gods and serving them.
