Luther shows the necessity of attending all services of the church. It seems that Martyn-Lloyd Jones has said something similar, and we must heed these words. Since the Spirit is sovereign, the Church does not know at what time He will move in a dramatic way. We need to be available to receive these blessings from the Spirit as His workman, the Minister of the Word, preaches for our blessing and benefit.
Since preachers have the office, the name, and the honor of being God’s co-workers, no one ought to think that he is so learned or so holy that he thinks he can miss the most insignificant of sermon.
