"Men who assume the responsibility of giving to the people the word from the mouth of God, make themselves accountable for the influence they exert on their hearers. If they are true men of God, they will know that the object of preaching is not to entertain. It is not merely to convey information, nor to convince the intellect. GW 152.1"
"Let a man so account of us, as of the ministers of Christ, and stewards of the mysteries of God."
The verse speaks of ministers as stewards, and EGW speaks of their accountability. While not a direct quote, it echoes the sentiment of responsibility and the sacredness of their role.
