In vv. 1-18 Jeremiah was writing according to his personal, human feeling, but in this verse his position and angle were changed from himself to God. He refers here to God’s eternal being and His eternal and unchanging government. Jerusalem was overthrown, the temple was burned down, and God’s people were carried away, but Jehovah, the Lord of the universe, remains to exercise His administration.
God’s eternal being and His throne are higher than His lovingkindness, compassions, and faithfulness (Lam. 3:22-23). God’s lovingkindness and compassions can fluctuate, but God’s person and His government remain unchanging forever. In the New Jerusalem, God will be fully unveiled in His person as the eternal King and in His government as His eternal, unshakable kingdom (Heb. 12:28; Rev. 22:3), both of which are the unshakable foundation of His dealing with His people.
