Prayer: One of the Surest Marks of a True Christian

J.C. Ryle:

A habit of prayer is one of the surest marks of a true Christian. All the children of God on earth are alike in this respect. From the moment there is any life and reality about their religion, they pray. Just as the first sign of the life of an infant when born into the world is the act of breathing, so the first act of men and women when they are born again is praying.
