The Puritans are often described as introspective and rarely as evangelists, which is a historical mistake. Joel Beeke investigates how they proclaimed what God's Word says about the salvation of sinners.

He describes their preaching - thoroughly biblical, unashamedly doctrinal, experimentally practical, holistically evangelistic and studiously symmetrical - along with their primary methods, plain preaching and catechetical evangelism, and the inward disposition that lay behind both. Short, pointed, and uncomfortable in the right places.
