Job 14:10

God gave David a special promise. His descendants would reign over Israel forever. Biblical history shows us how God kept this promise in an amazing way, despite the unfaithfulness of David’s descendants. He sent Jesus Christ, the ultimate Son of David, who will be King forever and ever — not only over Israel, but over all the nations.

The book of Job chronicles testing a righteous man's faith through suffering. Although Job's friends attempt to comfort him, it is only by God's revelation of His wisdom and might that Job finds true comfort. Even in deep suffering, God can do all things, and none of His purposes can be thwarted (Job 42:2).
