What the Bible says about Abuse of Body
(From Forerunner Commentary)
In verses 3-21, He gives instructions about what should be taken internally, what kinds of meats are suitable for intake from God's perspective. The eating habits of the Egyptians were certainly not up to God's standards, and He thus illuminated Israel on what was good as food for human consumption and what was not. In essence, God is concerned about what goes inside our bodies. Junk foods, of course, are not addressed, but God's intent is the same: Do not misuse the inside of the body.
Breaking the laws of physical health, such as lack of exercise and rest, injuring and abusing the body, unhygienic practices and poor nutrition, may also produce spiritual effects. Neglecting one's body, Paul says, is a sin of defiling what is holy, and God will punish for it. With an important addition, he repeats this three chapters later in I Corinthians 6:19-20, where he also ties in Christ's redemptive sacrifice for us. These types of sins are also forgiven. Our Savior's gift of His life covers it all!
