In Job Chapter 1:12 The Lord gave Satan the power to do anything he wanted to get Job to curse the Lord without touching him.
12: And the Lord said unto Satan, Behold, all that he hath is in thy power; only upon himself put not forth thine hand. So Satan went forth from the presence of the Lord.
In verses 15, 16, 17, 19. People were slain for the purpose of proving that job is loyal.
15: And the Sabeans fell upon them, and took them away; yea, they have slain the servants with the edge of the sword; and I only am escaped alone to tell thee.
16: While he was yet speaking, there came also another, and said, The fire of God is fallen from heaven, and hath burned up the sheep, and the servants, and consumed them; and I only am escaped alone to tell thee.
17: ...slain the servants with the edge of the sword
19: And, behold, there came a great wind from the wilderness, and smote the four corners of the house, and it fell upon the young men, and they are dead; and I only am escaped alone to tell thee.
Why would The Lord allow Satan to have the power to take other lives just for the purpose of proving that Job is a loyal servant?
