Some timely thoughts from Martin Luther and D. Martyn Lloyd-Jones, via Presbyterian Thoughts:
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.
[Luther wrote:] 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.
