Absolutes. Are you part of the 91.7% or the 8.3%?

Psalms 103:1-5 says that God forgives all our sins and heals all our diseases. This is an absolute. So if God did do this, then how much sickness should we be dealing with? If Jesus said, "It is finished." Then what else is there for Him to finish in the area of sickness and diseases? The power lies in our choises. Are we giving value to something that actully holds no value at all? Lets talk about it.
