"Many of our ministers can present to the people only a few doctrinal discourses. The same exertion and application which made them familiar with these points would enable them to gain an understanding of others. The prophecies and other doctrinal subjects should be thoroughly understood by all ministers. But some who have been preaching for years are content to confine themselves to a few subjects, being too indolent to search the Scriptures diligently and prayerfully, that they may become giants in the understanding of Bible doctrines and the practical lessons of Christ. GW 281.1"
"Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth."
Both passages emphasize the importance of diligent study, particularly for ministers or those teaching others. EGW's criticism of ministers who are 'too indolent to search the Scriptures' directly reflects the call to 'study to shew thyself approved unto God' in 2 Timothy 2:15.
