Read Proverbs 14:30 from your Bible
Every disease has its roots in sin. There was no sickness before sin came. God made provisions for everything in the Garden of Eden, but not for healing, because man was not created to be sick. But by one man sin came, and sin brought death, and everything that leads to death, including leukaemia, cancer, AIDS, name it.
Jesus said, “Thy sins are forgiven thee” is the same thing as saying, “Arise and be healed” (Matthew 9:6), because both sin and sickness have the same root. Every disease is a curse and a curse is as a result of sin (Deuteronomy 28:15-68).
The Bible calls all forms of sicknesses curses, whether fever, chest pain, bad eyesight, deafness, name it. No other theological or medical explanation, can be stronger than what the Bible has to say. Sin is at the root of every disease; and until righteousness takes over, sickness will continue. So let go of sin, so you can enjoy the newness of life in your health!
