Though you may not know Gerhard Tersteegen by name, you will likely find his hymn "Thou hidden love of God" in your hymnal. If you read further, you will see that this hymn was translated by none other than John Wesley - a great admirer of Tersteegen. Now you too can be inspired by the same words that set John Wesley and countless other religious leaders down the path to inner peace. The profound spiritual counsel of this 18th century pastor is presented in this volume in the form of short selections from 100 of his letters. Tersteegen's emphasis on heartfelt religious devotion, ethical purity, and charitable activity profoundly influenced the development of various Protestant denominations, including the Methodist movement. It is the beauty of Tersteegen's words that have kept his hymns popular for over 300 years, but it is his simple message of prayer and inwardness that is as timely today as it was when they were first written.
