Public Lectures by Physicians—One who is a physician and a religious teacher will find a work to do that will result in the salvation of souls. The form of sound words in religious teaching, sustained by a “Thus saith the Lord,” will have a saving influence. A physician can so express himself that he will be invited to speak before various companies, and will be received. As a teacher, a physician can watch his opportunities, for the Word of God is to go freely.—Letter 4, 1910.
