Unity of body and mind
The Bible clearly connected physical health with spiritual health. Paul wrote, “I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service” (Romans 12:1). The Christian does an act of spiritual worship by offering to God a holy and healthy body, along with a dedicated mind and heart. Because by so doing, he yields all there is of him to God’s hand, and unlocks the path for his full restoration to the divine image (Genesis 1:27).
Therefore, it is an act of religious service to preserve the physical health in the best possible state. For the believer glorifies God in his body (1 Corinthians 6:20) by showing a living example of God’s redeeming grace and by working with increased power and vitality in the mission of preaching the good news of the gospel to the world (1 Timothy 4:12).
Glorify God in diet and lifestyle
Paul sets forth a rule that is simple yet far reaching. He says, “Therefore, whether you eat or drink, or whatever you do, do all to the glory of God” (1 Corinthians 10:31). Mainly the direct application was to the issue of eating or drinking that which has been dedicated to idol worship. But this verse has a more compressive application which includes all kinds of food and drink.
Food and drink are of major importance in relation to the preservation of health. Many sickness that plague humanity are due to wrong practices in diet. God asks His children to take care of their bodies and fit them to be temples of His Spirit. Towards that end, a believer must learn how to choose his food and drink that will not harm his body but will enhance his health, both mental and physical. Therefore, he must abstain from addictive unhealthy substances and yield his mind and body to God’s plan (Proverbs 18:10; 1 Corinthians 15:31; 2 Corinthians 4:10; Colossians 3:17).
The believers’ ideal diet is the original diet provided by the Creator in Eden. God said, “See, I have given you every herb that yields seed which is on the face of all the earth, and every tree whose fruit yields seed; to you it shall be for food” (Genesis 1:29).
Ultimately, the Christian must do everything, in his daily life, so that God, not man, is honored. He should observe God’s “Eight Laws of Health” which are mainly: Nutrition, Exercise, Water, Sunshine, Temperance, Air, Rest, and Trust in God. These are God’s natural remedies that once kept in their proper way, help promote health and happiness.
God’s health promises
God promised the ancient Israelites that He will keep them in good health if they would obey His commands. He said, “If you diligently heed the voice of the Lord your God and do what is right in His sight, give ear to His commandments and keep all His statutes, I will put none of the diseases on you which I have brought on the Egyptians. For I am the Lord who heals you (Exodus 15:26 also Deuteronomy 7:12–15). And today, He renews the same promise to His children if they take into their bodies only those things that are in harmony with His laws (Genesis 1:29; 3:18; Leviticus 11:2–31; Ecclesiastes 10:17; 1 Corinthians 10:6).
Our lifestyle and diet contribute to sickness, affect our minds, and our general well-being. Daniel and his friends applied these principles. For in the court of Babylon, they gave an outstanding illustration of the blessings of God in their bodies (Daniel 1:12,18). Their pure lives and their harmonious development, physically, mentally, and spiritually, were a model of what God will do for those who offer themselves to Him and who seek to carry on His divine purpose.
