"The influence of such preachers is not pleasing to God. If any are brought out to receive the truth from their labors, they frequently imitate their preachers and come down to the same low level with them. It will be more difficult to remodel these and bring them into a right position, and teach them true order and love for discipline, than to labor to convert to the truth men and women who have never heard it. The Lord requires His ministers to be pure and holy, to rightly represent the principles of truth in their own lives, and by their example to bring others up upon a high level. 2T 614.2"
"Let no man despise thy youth; but be thou an example of the believers, in word, in conversation, in charity, in spirit, in faith, in purity."
Both passages emphasize the importance of leaders being examples to their followers. 1 Timothy 4:12 explicitly states this, and EGW echoes this principle by stating that ministers should 'rightly represent the principles of truth in their own lives, and by their example to bring others up upon a high level.'
"God requires all who profess to be His chosen people, though they are not teachers of the truth, to be careful to preserve personal cleanliness and purity, also cleanliness and order in their houses and upon their premises. We are examples to the world, living epistles known and read of all men. God requires all who profess godliness, and especially those who teach the truth to others, to abstain from all appearance of evil. 2T 614.3"
"Abstain from all appearance of evil."
EGW directly quotes 1 Thessalonians 5:22, indicating a clear and intentional allusion.
