Job 2:7
So went Satan forth from the presence of the LORD, and smote Job with sore boils from the sole of his foot unto his crown. So went Satan forth from the presence of the LORD, and smote Job with sore boils from the sole of his foot unto his crown.
Satan struck only because he was permitted to test, first sweeping away all that was possessed — flocks and herds, menservants and maidens, sons and daughters — and then smiting the man himself with sore boils from the sole of the foot to the crown. The blow was a severe and painful bodily affliction that left him seemingly forsaken by heaven and earth. Stripped of earthly treasures, bereaved of children, and made an object of loathing to friends, his condition appeared utter abandonment.
His suffering was not the result of a sinful life or a sinful course of life. His friends wrongly accused and blamed him as deserving punishment for his pain. By that false blame they misrepresented God.
Though anguished and perplexed, feeling that God's hand had touched him and pleading for relief, he held fast his faith and his sense of integrity. He preserved his integrity and faithfulness to God despite suffering and loss, remaining loyal through the affliction. His suffering did not mean God had forsaken him. In God's time he was lifted up, rewarded, and shown greater favor than before.
The verse reveals that Satan has the power of disease and death. He uses that power to annoy men and to enfeeble the race, learning in every age how to do it more effectively, so that the curse has become more visible and his power more plainly seen over time. Because of this work mankind has been degenerating and losing strength and comeliness, with every generation growing weaker, more subject to disease, and shorter in life. Those who lived in the days of Noah and Abraham were more noble in appearance and more like the angels in form, comeliness and strength.
