Job's Faith, Why So Strong?

It isn't over for Job yet

1 The Unseen World
-Satan went back to the throne of GOD to ask GOD for permission to torment Job still further
-Satan is given permission to take Job's health but not to kill him

2 Job's Discouragements
-His wife
-His three friends
-Saw his suffering and assumed a secret sin
-This is wrong and not true, as GOD said that Job's suffering was without cause

3 Job's Reaction
-It is foolish to think that the godly only receive good things and not bad
-He accepts it even though he doesn't understand it

The key to understanding Job
-Though He slay me, yet will I trust in Him (Job 13:15)

-Where did he get this strength from?
-Why was his faith so strong?
