*** km 2/89 p. 3 Our Identification as Jehovah's Witnesses ***
As ministers of the good news, we are known publicly as Jehovah's Witnesses. Our voluntary participation in the field service is motivated by love of God and neighbor. It is not carried on at the insistence of any man or organization but is according to our God-given commission to preach the "good news" and make disciples. (Matt. 24:14; 28:19, 20) Therefore, publishers do well to avoid representing themselves as agents or representatives of the Watchtower Bible and Tract Society of New York, Inc., or any other corporation used by "the faithful and discreet slave" to advance Kingdom interests.-Matt. 24:45-47.
