Do not act the part of a salesman in the house of God—I was shown that if the moral and intellectual faculties had not been clouded by wrong habits of living, ministers and people would have been quick to discern the evil results of mixing sacred and common things. Ministers have stood in the desk and preached a most solemn discourse, and then by introducing merchandise, and acting the part of a salesman, even in the house of God, they have diverted the minds of their hearers from the impressions received, and destroyed the fruit of their labor.—Testimonies for the Church 1:472. PaM 271.1
Ministers are to promote missionary work in all lands—No one who has given his life to God's work as His minister, lives for self. His work is to follow Christ, to be a willing agent and co-worker with the Master, receiving His Spirit day by day, and working as the Saviour worked, neither failing nor being discouraged. He is chosen of God as a faithful instrument to promote missionary work in all lands, and he must ponder well the path he follows.—Gospel Workers, 451. PaM 271.2
