Where mother came from.
*** Watchtower 1961 July 15 pp.431-2 Become Activated by the Spirit of Jehovah ***
6 From a study of God’s Word one appreciates that Jehovah does not dispense his dynamic energy through just any organization that chooses to label itself religious. Neither does God deal with individuals independently of his own wifely organization, the "mother" of all those dedicated to God. (Gal. 4:26) He has always had His channel of communication on earth through which his spirit operates. Remember how Miriam and Aaron tried to bypass this channel and almost lost their lives as a result? Only after Jesus had been baptized by Jehovah’s representative did he receive holy spirit and strength to enable him to do his powerful works. (Num. 12:1-16; Matt. 3:16; Acts 10:38) By and through this holy spirit Jesus aided those associated with him so they could understand the truth, and so they too could receive power to "cure sick people, raise up dead persons, make lepers clean, expel demons." Thus is emphasized the importance of association with Jehovah’s organization.-Matt. 10:8; Luke 24:45; 1 Cor. 2:10
