Thanks to the reborn zeal of these Christians, others were drawn to Jehovah’s light. To start with, the newcomers were anointed as additional members of the Israel of God. They are called kings at Isaiah 60:3, since they are to be coheirs with Christ in God’s heavenly Kingdom. (Revelation 20:6) Later, a great crowd of other sheep began to be drawn to Jehovah’s light. These are the “nations” mentioned in the prophecy.

¹⁰ Can you imagine Zion’s joy at having her children with her? Yet, Jehovah gives Zion additional reasons for joy. We read: “At that time you will see and certainly become radiant, and your heart will actually quiver and expand, because to you the wealthiness of the sea will direct itself; the very resources of the nations will come to you.” (Isaiah 60:5) In harmony with those prophetic words, since the 1930’s, multitudes of Christians whose hope is to live on earth forever have flocked to Zion. They have come out of “the sea” of mankind alienated from God and represent the resources of the nations. They are “the desirable things of all the nations.” (Haggai 2:7; Isaiah 57:20) Notice, too, that these “desirable things” do not go off to serve Jehovah each one in his own way. No, they add to the beauty of Zion by coming to worship in association with their anointed brothers, becoming “one flock” with them under “one shepherd.”​—John 10:16.
