The Book of Job wrests with human suffering and divine sovereignty. Job was complete in God. Job was righteous amid all his wealth. Job sanctified his children. When you fear God you fear nothing else, when you don't fear God you fear everything else.
Also a study on who the Sons of God are, God's sovereignty, the Old Testament Giants, and how the Throne Room functions and who has access.
Not all suffering is God's chastening; Job was a battleground. God is fully aware of any suffering or difficulty we face. It was allowed by Him to defeat Satan and bring Glory to Himself.
