Jas.5: The rich weren't ready for the last days—on Probing the Prophets with Rod
The conflict between the poor brother and the rich abuser comes to its climax in James 5. Ill-gotten silver and gold would simply “rust” away and be useless in the last days, the days of the judge, the soon-coming days they faced.
On the other hand, those abused by them could take comfort, knowing that the Judge was at the door already; but they needed to “endure until the end” (Matt. 24:13).
Patience, like in Job, has its reward; because the Lord is full of compassion.
