“Your Grand Instructor will no longer hide himself, and your eyes must become eyes seeing your Grand Instructor. And 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 30:20b, 21.b

¹⁸ Jehovah is the “Grand Instructor.” He has no equal as a teacher. How, though, can people ‘see’ and “hear” him? Jehovah reveals himself through his prophets, whose words are recorded in the Bible. (Amos 3:6, 7) Today, when faithful worshipers read the Bible, it is as if God’s fatherly voice is telling them the way to go and urging them to readjust their course of conduct so as to walk in it. Each Christian should listen carefully as Jehovah speaks through the pages of the Bible and through Bible-based publications provided by “the faithful and discreet slave.” (Matthew 24:45-47) Let each one apply himself to Bible reading, for ‘it means his life.’​—Deuteronomy 32:46, 47; Isaiah 48:17.
