In what way shall we attain to this settled happiness of soul? How shall we learn to enjoy God? How shall we obtain such an all-sufficient soul-satisfying portion in him as shall enable us to let go the things this world as vain and worthless in comparison? I answer, this happiness is to be obtained through the study of Holy Scriptures. God has therein revealed Himself unto us in the face of Jesus Christ.
