Sin and sickness are not from God. The purpose of the first coming of Jesus was to make a way of escape from the evil which Satan, and ultimately man, by his disobedience, brought into the world: "For this purpose the Son of God was manifested, to destroy the works of the devil!" - 1 John 3:8. However, this is only in part today, none of us is perfect in ourselves, we live in a world of sin and sickness and are surrounded by them. When Christ returns we shall be taken out of this world into the Kingdom of Heaven, then there will be no more sin, sickness or death. Until then, walking by faith, we must overcome sin - and temptation - and sickness. The Bible makes it clear, the wages of sin is death, but the gift of God is eternal life. Just as we receive wages for the employment we undertake, so spiritually we receive wages too: if we choose to work for the devil and live in sin, our wages are death - if we choose to work for God and follow His commands, our wage is eternal life.
