If we can be healed from a disease by stopping a destructive behavior, we can also prevent the same diseases by stopping the destructive behavior before we get the disease. If you have not read the information under the heading Spiritual Root of Disease please do so. Medical science, psychology and Scripture are all very clear that there is a connection between negative thoughts and emotions and disease. Negative emotions play a role in creating disease and in making our recovery more difficult. Negative emotions suppress the immune system and when our immune system is suppressed many different diseases can take over. Negative emotions also cause our endocrine system (hormones) to be out of balance. There are hundreds of clinical trials that prove negative thoughts and emotions (sins) can cause or make a disease worse. It has also been demonstrated that stopping the negative thought processes can and does result in healing. It is also logical that if we stop the destructive behavior (negative emotions) we will not get the diseases. Science also clearly shows that positive emotions will enhance our immune system and promote healing. With a strong immune system we will be able to fight off disease, thus preventing the diseases. My book, In His Own Image, quotes over 200 clinical trials and medical sources that substantiate these claims.
