John Wesley was an Anglican priest and major leader in the eighteenth-century Evangelical awakening whose theology and practice continues to influence the church today. This book tells how his own search for a heart renewed in love ultimately led him to a fresh vision of the way of salvation, one that is centered on sanctification, empowered by the Holy Spirit, and available to all. Transcending the theological dichotomies of his day, Wesley developed a distinctive Protestant tradition that continues to shape Methodist and Holiness Christians, and has had a significant impact on Pentecostalism. It was Wesley's optimism of grace that gave his Methodists and generations to come a vibrant hope that hearts and lives, churches, and the world at large can all be changed by the power of God's amazing love.
