Just wondering

I am wondering about two things:

1. If the wages of sin are death and disease is incipient death and Jesus has paid for all sin then why should I ever be sick? Another like it, but more problematic: If the wages of sin are death and Jesus paid for all sin then why do I have to die? Should I not be free of death if I am free of sin?

2. Is it correct to say that Jesus' death on the cross has purchased my salvation? If Jesus died on the cross and they took him down and that was it, would I be saved? I don't think so but I think a whole lot of the Body of Christ thinks so.
