Written in times of revival, this book was the result of the reflections of a pastor who looked beyond the profession of faith, a prayer of salvation or spiritual experience. He realized that the way that leads to union with God is not easy, and understand with his contemporary, Jonathan Edwards, that “the righteous scarcely be saved” as Peter says in his first epistle, chapter four verse eighteen. The believer must contend with powerful enemies, and if God did not have with us, we would soon be defeated and destroyed. But God takes us, cleanses us, strengthens us, and transforms us, leaving us equipped to enter into heavenly glory. What is being a Christian? What are the spiritual signs palpably showing ourselves and others that we are born of God? How can we ensure that we have true spiritual life? These questions are very important and each person must examine itself.
