There is sure a good glimpse into God's character in these words from Job. We are reminded that He holds strength, wisdom, power, and authority beyond any other. We are also reminded that He is the source of our hope. Despite all of Job's experiences, it's really incredible to me that he can say, "Though [God] slay me, I will hope in him" (13:15). God has the right to do as He desires – no matter what that means for us! Job didn't deserve God's grace any more than you or I, and even though he faced horrible tragedy, Job realized that his only hope for anything in life could come from the author of it all. Job's friends tried to pull that hope away from him, but thankfully he clung very tightly to it. It's no wonder that God used him as an example to Satan as one who feared him and turned from evil.
Being one who has felt like Job I have found that the people around us try to show their caring but since they have no base reference to what you are going through they have a hard time understand ones knowledge that God can do anything. At times we do not understand why’s in life. Job just understood that God was in control.
