In our study of Isaiah chapter twenty six, we look at the unification of Jew and Gentile into one nation and the expectation of the resurrection. This theme continues the celebration during the Millennial Reign and looks forward to the resurrection of the dead and the final judgment for all of mankind.
"In that day this song will be sung in the land of Judah: We have a strong city; God makes salvation its walls and ramparts." NIV translation
In the Hebrew, this verse gives you the feeling of someone strolling along and singing in reflection on what God has done. The song remembers the fact that God watched over His people and the city delivering them from the enemy and uniting them together.
"Open the gates that the righteous nation may enter, the nation that keeps faith. You will keep in perfect peace those whose minds are steadfast, because they trust in you." NIV translation
The "righteous nation" refers to Gentiles that had guarded the truth of the gospel of Jesus Christ. The word that is translated here as "steadfast" is the Hebrew word "camak" and it speaks of taking hold or grabbing onto something. Jesus said that he was The Way, The Truth, and The Life and that nobody would enter the kingdom except through Him.
The word that is translated as "trust" is the Hebrew word "batach" which describes boldness or confidence. This passage speaks of both Jew and Gentile that have confidently accepted the gospel and held onto it through the Great Tribulation. They have now become one nation in Christ.
The "perfect peace" that is spoken of is commonly called "Shabbat shalom" which means "Sabbath peace". This is a complete peace that is based on freedom from work as when the Sabbath is observed. This is a contrast to religion and man's efforts to reach God. When you trust in your own efforts, you will not know whether they were sufficient until the final judgment. That doubt and worry is the opposite of peace and can be avoided by resting in the completed work of Jesus Christ on our behalf.
Religion in any form is used by the devil to bring division and conflict which is why we have so much war in the world today. As world religion attempts to replace the completed work of Jesus Christ, the wars and rumors of wars will only increase.
