Luther on Call to the Ministry

Luther on God’s call to the ministry:

Tarry, beloved, until God bid thee, until thou hast certainty and boldness of heart. Yea, wert thou wiser and cleverer than Solomon and Daniel, thou shouldest flee as from hell from speaking a single word, except thou shouldest be bidden and called thereto. If God need thee, He will surely call thee. If He call thee not, beloved, let not thy skill tear open thy belly. Thou thinkest foolishly of the good and piety…thou wouldest achieve. Believe me, none will do any good by preaching except he who is bidden and forced to preach without his own will or desire. For we have but one Master, our Lord Jesus Christ, who alone teacheth and bringeth forth fruit through His servants, whom He hath called thereto. But whoso teacheth uncalled, teacheth not without harm, both to himself and the hearers, for that Christ is not with him.
