Zion will be redeemed with justice, her penitent ones with righteousness.  But rebels and sinners will both be broken, and those who forsake the LORD will perish.

Repentance brings redemption and righteousness – sounds like the “3 Rs” of spirituality.  Those who forsake the Lord will perish.

Here it is in the prophecy of Isaiah – the Gospel, pure and simple.  Repent and be redeemed, or forsake God and perish.
