17 If Christian parents responsibly decide to provide their children with further education after high school, that is their prerogative. The period of these studies would vary according to the type of trade or occupation selected. For financial reasons and in order to enable their children to get into the full-time service as quickly as possible, many Christian parents have chosen for them short-term study programs in vocational or technical schools. In some cases youths have needed to be apprenticed to some trade but always with a full life of service to Jehovah as the goal.
18 If additional courses are taken, certainly the motive should not be to shine scholastically or to carve out a prestigious worldly career. Courses should be chosen with care. This magazine has placed emphasis on the dangers of higher learning, and justifiably so, for much higher education opposes the “healthful teaching” of the Bible. (Titus 2:1; 1 Timothy 6:20, 21) Further, since the 1960’s, many schools of advanced learning have become hotbeds of lawlessness and immorality. “The faithful and discreet slave” has strongly discouraged entering that kind of environment. (Matthew 24:12, 45) It must be admitted, however, that nowadays youngsters meet up with these same dangers in high schools and technical colleges and even in the workplace.—1 John 5:19.
19 Should supplementary education be decided upon, a young Witness would do well, if at all possible, to take this while living at home, thus being able to maintain normal Christian study habits, meeting attendance, and preaching activity. At the outset a proper stand should also be taken on Bible principles. It should be remembered that Daniel and his three Hebrew companions were captives in exile when they were obliged to undertake advanced studies in Babylon, but they consistently kept their integrity. (Daniel, chapter 1) While placing spiritual interests first, young Witnesses in a number of countries have taken courses to equip themselves for part-time work as accountants, tradesmen, teachers, translators, interpreters, or other occupations that supported them adequately in their primary career of pioneering. (Matthew 6:33) A number of these youths have later become traveling overseers or Bethel volunteers.
