SPEAKING of the time in which we are living, Jehovah foretold: “In those days ten men out of all the languages of the nations will take hold, yes, they will take firm hold of the robe of a Jew, saying: ‘We want to go with you, for we have heard that God is with you people.’” (Zech. 8:23) Like the figurative ten men, those who have an earthly hope have taken “firm hold of the robe of a Jew.” They are proud to associate with the spirit-anointed “Israel of God,” knowing that Jehovah is blessing his anointed ones.—Gal. 6:16.
If it is not possible to know with certainty the names of all spiritual Israelites on earth today, how can members of the other sheep “go with” them? Notice what the prophecy in Zechariah states concerning the figurative ten men. These ones would “take firm hold of the robe of a Jew, saying: ‘We want to go with you, for we have heard that God is with you people.’” Although only one Jew is mentioned here, in both instances the pronoun “you” refers to more than one person. This spiritual Jew must, then, be a composite person, not just one individual! So it is not necessary to identify every spiritual Jew and then go with him or her. Rather, we need to identify these ones as a group and then support them as such. In no way do the Scriptures encourage us to follow an individual. Jesus is our Leader.—Matt. 23:10.
