Satan accused God of bribing Job. This defiant spirit creature claimed that if Job was stripped of his wealth and his health, he would curse Yahweh. By extension, Satan was asserting that no human would love and be loyal to God in the face of suffering.
That challenge had global and enduring impact. The issues that Satan raised had to be settled. Thus, God gave Satan freedom to act against Job, and Satan brought those various forms of suffering on the man.
Job did not and could not know of the universal issue that was raised in the heavens. And Satan arranged things so that it appeared as if God were causing all of Job’s calamities. For example, when lightning struck Job’s flocks of sheep, the surviving attendant concluded that it was “the very fire of God.” Although Job did not know why these things were happening, he would not curse or reject God.
If you analyze the circumstances behind Job’s experience, you will see that the issue is, Will humans serve Yahweh out of love, despite troubles? Job helped to answer that. Only true love for God could have moved a person to remain faithful to Yahweh, which is what Job did. What a testimony against Satan’s false accusations! This case, however, did not begin and end with Job back then, it has extended for centuries. We are involved too.
