I think a lot of people struggle with those same issues.

The way I view it, we have to go right back to the beginning when God gave mankind (in Adam) dominion over the earth and everything in it. At this time, the earth was perfect and cancer did not exist.

Then along came that sneaky serpent and tempted Adam and Eve to disobey God and thus obey/serve the serpent. In doing so, they inadvertently brought or allowed death and decay (and cancer) into the world through their choice.

Satan wanted the earth for himself, but the only way to get it was through man's choice, because man had been given the dominion mandate.

This is still true today, and mankind is continually tempted to serve the devil, though it is usually not portrayed in such black and white terms. However, the same consequence is still in effect today - the Bible says the wages of sin is death. As we choose sin, it allows death into ourselves and the world around us.

Jesus offers the only true escape from this cycle, and an opportunity for those who believe in him to become sons of God and take back their rightful dominion over the earth. As more people enter into this experience, death is prevented from reaching its fuller expression and life is allowed to come forth.

I don't pretend to have all or any answers regarding cancer, though I know that it has come into the world and thus our lives through either our own choices or those of others. Yes, there are casualties in this war and collateral damage.

However, I believe that to those who are called sons of God, the real question is not "God, why is there cancer in the world?" But instead, the real question is God asking us - his sons - "Son, why is there cancer in the world?"
