The Kingdom of God in the Soul is a book by Joannes Evangelista of Bois-le-Duc (also known as Father John Evangelist), originally published in the 17th century. The work, dealing with inner spiritual life and devotion to Christ, was later edited by the Benedictine Nuns of Stanbrook and published in a 1930s edition as part of the 'Capuchin Classics' series, with an introduction by Father Cuthbert.
