Today, there are many teen-age baptized servants of Jehovah. Their personal study, preparation for meetings and sharing in the Theocratic Ministry School have given them a basic knowledge of Bible truth for Christian preaching. They have also benefited by education in the public schools. But how far should they go with a secular education? It would hardly be consistent for such a youth, of his own choice, to pursue extensive secular studies beyond what is required by the law and by his parents. According to First Timothy 6:20 it would be unwise to fill one’s mind with philosophies of imperfect men: “O Timothy, guard what is laid up in trust with you, turning away from the empty speeches that violate what is holy and from the contradictions of the falsely called ‘knowledge.’” For this reason additional years of college education may present snares. One may become “brainwashed” by human philosophies so that faith in God and the Bible is destroyed. (Col. 2:8) Many college and university courses are based on false theories, such as evolution, that bolster the old system of things, which will soon pass away forever. (1 John 2:17) A goodly number of the professors have no faith in God or in the Bible and actively teach their godless beliefs. Moreover, there is the corrupting influence that the college atmosphere often has on morals, including the danger of drug addiction.
