If there be any man under heaven, who is compelled to carry out the precept – “Pray without ceasing,” surely it is the Christian minister. He has peculiar temptations, special trials, singular difficulties, and remarkable duties; he has to deal with God in relationships full of awe, and with men in mysterious interests; he therefore needs much more grace than common men, and as he knows this, he is led constantly to cry to the strong for strength, and say, “I will lift up mine eyes unto the hills, from whence cometh my help.”

Charles H. Spurgeon
