One of the most important books about the subject of Christian assurance ever put into print. Having a healthy and well-founded assurance of being “in Christ” is vital to strong Christian growth and experience. There is no higher privilege than to be a child of God and to *know* that you are! — for a strong assurance brings, along with it, joy and peace in believing, strength and boldness in our witness.

This abundantly clear and valuable work, first published in 1654, still reads today like a pastor conversing with his friend.
