Charles Spurgeon (1834-1892) was a man of Bible study, prayer, teaching and preaching. It has been estimated that he preached to about 10 million people.

Here is a great quote on prayer from C.H. Spurgeon:  Of course the preacher is above all others distinguished as a man of prayer.  He prays as an ordinary Christian, else he were a hypocrite. He prays more than ordinary Christians, else he were disqualified for the office which he has undertaken.   

 So prayer is an important aspect to our life.
