Appropriately, then, the prophecy at Isaiah chapter 26, verses 1 to 6, sets forth an exultant song of praise to the Sovereign Lord Jehovah.

Open the gates, you men, that the righteous nation that is keeping faithful conduct may enter.

3. (a) What is “the righteous nation,” and who have entered through its open “gates”? (b) How is it that Jehovah’s organization moves forward unitedly despite enemy efforts to break it up?

³ The Lord Jehovah​—Jah Jehovah—​will indeed abase the proud and deliver those who trust in him always. Though once a “little one,” spiritual Israel has become “a mighty nation,” “the righteous nation.” Through the open “gates” of Jehovah’s citylike organization, there has entered also a mighty throng of goodwill companions numbering more than three million. Together they make up an international brotherhood, the population of which exceeds that of at least 57 of the nations making up the so-called United Nations. But God’s “nation” and those associating with it are truly united. Earth wide, their inclination is to obey his righteous principles. The organizational “walls” of God’s “nation” provide a bulwark against Satan’s efforts to tamper with its faithful conduct in support of truth.
