Keystones Volume 2: Acts through Philemon.
A keystone is the linchpin, the centerpiece, that holds a bridge or arch together.
Through his historical and pastoral studies, Dr. Grant locked-in on a method of Scripture study from 200 years ago. In the early 1800s in Scotland, Pastor Thomas 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.
