“Say to the righteous that it will go well with them…”
Why does he stop to tell them this? Obviously there is a reason why Isaiah stops midstream of his sermon to speak to the righteous, In this sermon where God is going to remove men from their ordained place of leadership and all things begin to unravel He needs to speak to the remnant for a moment. Not all is lost. It looks like it is. But no, not for the redeemed righteous.
When the Lord begins to remove “both supply and support” (Isaiah 3:1) of a nations strength, the redeemed must remain unstained by the world and sustained by the Word of God.
When God begins the removal of the mighty man, the warrior, the discerning judge, the elder statesmen, the leaders of men of valor, honorable men, counselors, men of craft and skill and the faithful herald of the oracles of heaven watch for who he He will replace them with. Watch with a praying voice to God for mercy.
He will replace reason with capricious children who will rule and oppress. He will give a nation that pridefully turns their back against Him what they deserve; rude, arrogant, disrespectful insolent, rash, and set them on a reckless path to failure. “Do not be deceived” by this, “God is not mocked”. “A man (a family, a church, a nation) reaps what he sows.” (Galatians 6:7-10)
This reaping what we sow goes both ways. The evil will reap evil. The righteous will reap righteousness.
This is a marvelous news to fall upon the ears of men. “They will eat the fruit of their actions.” (Isaiah 3:10)
