What I think

Hereditary disease? I think they that it is as John 9 says, Neither this man nor the parents sinned but this happened so that the work of God might be displayed in his life. No doubt through Adam, we as his decendents are plagued with this hereditary disease of sin, but it did not happened so that we may suffer. God definitely do not rejoice at you suffering over such pain for no good reason. All this happened that GOD MIGHT BE DISPLAYED IN HIS LIFE! So lets pray and believe together that God will heal!
