“Then said Hezekiah to Isaiah, "The word of the LORD that you have spoken is good." For he thought, "Why not, if there will be peace and security in my days?" (v19). King Hezekiah remained faithful to the Lord through times of difficulty and threats from the Assyrian Empire. However, his faith and hope were centered on what God could do in his own lifetime; he didn’t care very much about the legacy he was leaving for future generations. He didn’t take responsibility for what would happen after he died (v21).
Our concern for “peace and security” is shallow unless it includes those beyond our family and beyond our own generation. We want God’s good word for others, too (v19).
