God gave health rules in the Bible because He created the human body and knows what is best for it. In Leviticus 11 and Deuteronomy 14, God very clearly points out the clean and unclean animals, and pig is among the unclean animals. God made the big for the same purpose that He made the buzzard–as a scavenger to clean up garbage.
Following God’s principles results in health. “The Lord commanded us to observe all these statutes, to fear the Lord our God, for our good always, that He might preserve us alive” (Deuteronomy 6:24). “You shall serve the Lord your God, and He will bless your bread and your water. And I will take sickness away from the midst of you” (Exodus 23:25).
The Bible says that anyone who eats pig meat and other unclean things that are an “abomination” will be destroyed at the coming of the Lord. “Behold, the Lord will come with fire … and by His sword the Lord will judge all flesh; and the slain of the Lord shall be many. Those who sanctify themselves and purify themselves … eating swine’s flesh and the abomination and the mouse, shall be consumed together” (Isaiah 66:15–17).
Some argue that the death of Christ did away with the health laws of the Mosaic law but Christ’s death did not in any way affect or change these health laws. In fact, these health laws were given even before the Jews, for “The Lord said to Noah, … ‘take with you seven each of every clean animal … two each of animals that are unclean’” (Genesis 7:1, 2). Noah lived long before any Jews existed, and he knew of the clean and unclean animals, because he took into the ark the clean ones by sevens and the unclean ones by twos. These health laws are for all people for all time.
