The student of John Calvin is aware of his extensive writing on the subject of prayer in his famous, The Institutes for the Christian Religion. Calvin understood prayer to be vital in the Christian life and viewed it as the “chief exercise of faith.” For centuries, with few exceptions, Calvin’s instruction on prayer has remained buried within the Institutes. Given that this work seems daunting for most, Calvin’s practical teaching on prayer has been extracted from his larger work and is now available to you in, Prayer: The Chief Exercise of Faith. Calvin never thought prayer was a vain exercise to a God unconcerned with the welfare of his people. He saw prayer as an intimate communion with the living God who cared enough about his own people that he sent his Son, the Lord Jesus Christ, to be the mediator between God and man. Use this little volume as a tool for yourself and others as you ascend to God in prayer without ceasing.
