Every rational being wishes to be healthy, wealthy, fulfilled and enjoy longevity. The desire to live long and be healthy is scriptural. Psalm 91:16 says,
“With long life will I satisfy him, and shew him my salvation.”
Man is a tripartite being. The Bible teaches that man consists of the spirit, soul and body. God is interested in our good health (3 John 1:2). He desires for us to be sound and complete in our spirit, soul and body. The working of wholeness in man starts in his spirit. It begins when God touches our spirit by the Holy Ghost (1 Corinthians 12:3). Has your spirit been touched by the Holy Spirit? The first miracle God does is to liberate man’s spirit from sin. He justifies us from sin and reconnects our spirit man to Himself (1 Corinthians 6:11). He then continually bears witness with our spirit that we are God’s children (Romans 8:16). After releasing our spirit from sin, the Holy Spirit works His way to our soul to heal and restore it. The soul of man is the seat of his emotions, intellect and will. The soul is the dwelling place of healthy and unhealthy emotions. It is thus possible for the soul to be healthy or sick.
 
The human body is that part of man which is aware of and interacts with the tangible, empirical world. The whole body of man is built around a bony framework of skeleton and consists of a great number of different parts. The human body consists primarily of cells, which together form tissues, which form organs, which work together as systems to carry out specific functions. It is worth noting that healthy living guarantees longevity. To enjoy longevity, you need to eat proper balanced diets. Experts in nutrition teach that our foods can be classified into two classes. One class consists of fruits and vegetables. The other class consist of fats, starch and proteins. A proper balance of these two classes of food will provide good health and a long life. An improper balance will bring poor health, sickness and can result in early death. Fruits and vegetables provide vitamins and minerals. Proteins supply building blocks for the body. Fats and starch supply heat and energy to the body. According to many health books, we should eat about 75% fruits and vegetables, while 25% should be protein, fats and starch. This 75 : 25 ratio should form the basis of the daily diet of every living person. To obtain and maintain good health, you must eat foods that contain generous amounts of vitamins and minerals. Foods low in vitamins and minerals lead to poor health, ailments, suffering and death. Enjoying longevity in good health is however not limited to the food you eat. Your state of mind and pattern of life can either accelerate or slow down the aging process. These also affect your good health. In addition, learn to exercise your body. Don’t forget: “bodily exercise profiteth little.”
