I think that we can find bible referencing that pretty comprehensively infers that yes, illness is a result of sin. If you want me to put some references here i can, but then you could easily find them yourself and given you appear somewhat resistant to biblical theology, perhaps its important you go searching for yourself if it really interests you. You would gain a lot more from your own study than someone raming bible verses down your throat.
What i will do is just quote one verse from the last book of the bible that clearly infers illness is a result of sinâŚ
Revelation 21 (the apostle John is quoting Isaiah 65:17-25 here)
1Then I saw a new heaven and a new earth,a for the first heaven and earth had passed away, and the sea was no more. 2I saw the holy city, the new Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband.
3And I heard a loud voice from the throne saying:
âBehold, the dwelling place of God is with man,
and He will dwell with them.
They will be His people,
and God Himself will be with them as their God.b
4âHe will wipe away every tear from their eyes,âc
and there will be no more death
or mourning or crying or pain,
for the former things have passed away.â
Oh, and consider the story of Lazurus. Jesus was informed that Lazurus was sick and needed his help. Jesus did not immediately go to Lazurus aid and as a result he died. Christ then raised him from the dead. Clearly infering that death is not something God wants to continue beyond the fulfillment of the plan of salvation (ie the second coming). It is Gods intention that there will be no more sickness and death and in order to achieve that end, he will wipe sin from existence!
