‘The Religious Affections’ is quite possibly one of the most important books ever written by America's greatest theologian Jonathan Edwards in 1746. Edwards wrote the Treatise to explain how true religious conversion to Christianity occurs. He describes how emotion and intellect both play a role, but ‘converting grace’ is what causes Christians to ‘awaken’ to see that forgiveness is available to all who have faith that Jesus' sacrifice atones for all sins. This is one of the unsurpassed religious masterpieces ever produced, which distinguishes between true and false religion by defining a believer's correct affections and explaining their importance. Edwards further identifies the distinction between genuine-seeming and legitimate affections. Essential reading for divinity students and those studying American religious history.
