“Go out from Babylon, flee from Chaldea, declare this with a shout of joy, proclaim it, send it out to the end of the earth; say, "The LORD has redeemed his servant Jacob!” (48:20). Because of His love, God called His own people to reject the idolatry and sinful practices of the pagan Babylonians. Their glittering, pleasure-loving lifestyles and their “sorceries and enchantments” (47:8-10) would end in terrible suffering (47:2-3). God warned His people that they could not claim the name “Israel” yet behave like Babylonians (48:1).
“Then your peace would have been like a river, and your righteousness like the waves of the sea” (48:18). God calls us to pursue His holiness because He wants us to live in peace.
