In an era of easy-believism and cheap grace, I.C. Herendeen poses an inescapable and provocative question: Is personal holiness merely an option for the elite believer, or is it an absolute requirement for eternal salvation? This theological classic rigorously examines Scripture to demonstrate that justification and sanctification are inseparable. The author argues with urgent clarity that a faith which fails to produce a transformed life separated from sin is a dead faith. This work serves as a solemn call for self-examination, challenging the reader to seek not only forgiveness but the purity without which "no one will see the Lord."
