When Jesus healed the sick man, He also addressed his sin. This brings up the theology of sin and sickness. Even though the modern world would like to ignore the connection between sin and sickness, what we discover in the Scriptures is that the sovereign God who rules over all things also orchestrates human sickness and even uses it at times to chastise people of their sin. In this sermon, the wider scope of connection between sin and sickness is examined, looking at the supporting Biblical evidence in both the Old and New Testaments. The three truths regarding sin and sickness seen in Scripture are: 1) All sicknesses ultimately arise from original sin. 2) Some sicknesses directly arise from personal sin. 3) Some sicknesses directly arise from God’s other purposes.

Immediately the man became well, and picked up his pallet and began to walk.
Now it was the Sabbath on that day. So the Jews were saying to the man who was cured, “It is the Sabbath, and it is not permissible for you to carry your pallet.” But he answered them, “He who made me well was the one who said to me, ‘Pick up your pallet and walk.’” They asked him, “Who is the man who said to you, ‘Pick up your pallet and walk’?” But the man who was healed did not know who it was, for Jesus had slipped away while there was a crowd in that place. Afterward Jesus found him in the temple and said to him, “Behold, you have become well; do not sin anymore, so that nothing worse happens to you.” The man went away, and told the Jews that it was Jesus who had made him well. For this reason the Jews were persecuting Jesus, because He was doing these things on the Sabbath. But He answered them, “My Father is working until now, and I Myself am working.”
For this reason therefore the Jews were seeking all the more to kill Him, because He not only was breaking the Sabbath, but also was calling God His own Father, making Himself equal with God.
