Do You Pray? By J.C. Ryle
Never be surprised if you hear ministers of the gospel dwelling much on the importance of prayer. This is the point we want to bring you to; we want to know that you pray. Your views of doctrine may be correct.
Your love of Protestantism may be warm and unmistakable. But still this may be nothing more than head knowledge and party spirit. We want to know whether you are actually acquainted with the throne of grace, and whether you can speak to God as well as speak about God. Do you wish to find out whether you are a true Christian? Then rest assured that my question is of the very first importance – Do you pray?
