Henry W. Wright shares many insights into why mankind has disease. It is not that God cannot heal or that He doesn’t want to; the problem is that man doesn’t understand disease. We have gone into captivity and are perishing because of either lack of knowledge or just no knowledge at all. My investigation over the years, from the Scriptures and by practical discernment, has unearthed many spiritual roots and blocks to healing. In fact, the basic principles that, when applied, will move the hand of God to heal, are the same that, when applied, will prevent disease.
