Similarly today, Jehovah’s Witnesses rejoice to learn of organizational decisions and clarifications of doctrine that promote the spiritual health of God’s people and the advancement of Jehovah’s work. (Compare Titus 2:1.) But it is no longer necessary for the Governing Body to write letters of instruction by hand and to circulate these by messengers traveling on foot. Modern means of communication and printing facilities in more than 30 Watch Tower branches around the earth have made it possible to convey “the good news of the word of Jehovah” to the millions of God’s people in a minimum of time. This is done principally through the Watchtower magazine. Thus, the congregations worldwide continue “to be made firm in the faith and to increase in number from day to day.”​—Acts 15:30–16:5.

Unquestionably, The Watchtower has been used mightily by our Grand Instructor, Jehovah God, in fulfilling the promise: “Happy are all those keeping in expectation of him. . . . Your own ears will hear a word behind you saying: ‘This is the way. Walk in it, you people,’ in case you people should go to the right or in case you should go to the left.”​—Isaiah 30:18-21.
