Some who enter the ministry do not feel the burden of the work. They have false ideas of the qualifications of a minister. They think that it requires little close study of the sciences or of the word of God in order to gain a fitness for the ministry. Some who are teaching present truth are so deficient in Bible knowledge that it is difficult for them to quote a text of Scripture correctly from memory. By blundering along in the awkward manner that they do, they sin against God. They wrest the Scriptures, and make the Bible say things that are not written therein. GW 105.2
Some think that an education or a thorough knowledge of the Scriptures is of little consequence if only a man has the Spirit. But God never sends His Spirit to sanction ignorance. He may and does pity and bless those who are so situated that it is impossible for them to obtain an education; and sometimes He condescends to make His strength perfect in their weakness. But it is the duty of such to study His word. A lack of knowledge in the sciences is no excuse for a neglect of Bible study; for the words of inspiration are so plain that the unlearned may understand them. GW 105.3
