In that day shall this song be sung in the land of Judah; We have a strong city; salvation will God appoint for walls and bulwarks. Open ye the gates, that the righteous nation which keepeth the truth may enter in. Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee. Trust ye in the LORD for ever: for in the LORD JEHOVAH is everlasting strength:
Isaiah 26:1-4
Isaiah's ministry occurred in a time when the kingdom of Judah was facing grave threats. It was during the reign of Hezekiah that the northern kingdom of Israel fell to the Assyrians, and the Assyrians had their sights set on Jerusalem next. In fact the Assyrian king Sennacherib planned to destroy Judah, but God intervened and miraculously delivered the people. “And it came to pass that night, that the angel of the LORD went out, and smote in the camp of the Assyrians an hundred fourscore and five thousand: and when they arose early in the morning, behold, they were all dead corpses” (2 Kings 19:35).
Yet despite all the threats facing God's chosen people, Isaiah encouraged them to trust in God and live in peace. The world's idea is that we can have peace when we are in good health, when there is plenty of money in the bank, when our jobs are secure, and when there are no threats on the horizon. Because we live in a fallen world, we are not likely to experience this kind of prosperity in every area of life for long, if we ever experience it at all.
God's love and care and provision for us are not a guarantee that nothing will ever go wrong. They are a guarantee that if we are willing to trust His plan over our own ideas, we can live in peace no matter what is going on around us. The Lord strengthens and empowers those who choose to turn to Him for help rather than allowing worry to fill their minds, and He gives peace that cannot be explained. “And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus” (Philippians 4:7).
