Remarkable advances in science have led to the cure of such dreaded diseases as polio and tuberculosis. But, because much of the disease and illness people experience is caused by sin and by ignoring principles of healthy living, there will never be a cure for all disease until Satan’s power is done away with.
Our bodies are only a part of what makes us human beings. We also have souls and spirits (see I Thessalonians 5:23). The body is the physical part of our nature. The soul corresponds to the mind. The spirit is that part of us that sets us apart from the animals, that stamps upon us the image of God. The spirit is the part of us that yearns for communion with God. If the spirit in us is not in tune with God, then you do not have access to the source of healing. If you lived in the perfect presence of God, there could be neither sickness nor death. There would not be infection or disease because such things cannot exist in the presence of God.
Some disease is caused directly by sin. Much sickness is the result of deep-rooted bitterness and uncontrolled stress. When people refuse to forgive or when they let themselves be “stressed out” by the pressures the world puts on them, that frequently leads to sickness. Those who live harried and hurried lives frequently develop ulcers, arthritis, high blood pressure, asthma, and similar ailments. Alcohol and cigarettes are also great contributors to disease because they weaken the human body.
Another reason for disease is that much of the food we eat contains poison and unhealthy additives. Sugar and salt and white flour and other harmful substances weaken our bodies when used in excess. We do not get enough of the natural nutrients we should have. We try to milk too much out of our land, and, in doing so, we wind up damaging the crops we grow for food. When we eat what is contaminated, our bodies are harmed also.
There will never be a decrease in diseases until people learn to eat properly, exercise properly, treat their bodies properly, and stop ingesting chemicals and other foreign substances that hurt their bodies. Nor will disease decrease while people continue polluting the water and air with carcinogens and fighting wars that destroy vegetation, uproot whole nations, and bring about famine. All these things are contributors to disease–and disease, because of infection and contagion, has a way of growing.
Sickness and disease will be a part of life on this planet until Jesus comes back. When He comes, He will set things properly in order, and there will be no more sickness and no more death. That is the promise we have from God. In Revelation 22:2, we are told that the heavenly city of New Jerusalem will contain a tree whose leaves “were for the healing of the nations.” We are reminded in Revelation 21:4 that when we dwell in the presence of God, “There will be no more death, nor sorrow, nor crying; and there shall be no more pain, for the former things have passed away.” Man, through his own efforts, will never find a cure for all diseases. But Jesus, when He returns to earth, will do away with disease and sickness forever.
