Keystones: Volume 1: The Four Gospels

A keystone is the linchpin, the centerpiece, that holds a bridge or arch together..Chalmers desperately wanted his students to mine the riches of Scripture- and then hide it in their hearts..He identified the key verse from every chapter of every book in the New Testament and created a tool that identified the passages which were, in his mind, keystones..The result was a survey and systematic theology which his parishioners studied each day.
