Dane Ortlund quoting Jonathan Edwards:
[It is the] sight of the divine beauty of Christ that bows the wills and draws the hearts of men. A sight of the greatness of God in his attributes, may overwhelm men, and be more than they can endure; but the enmity and opposition of the heart, may remain in its full strength, and the will remain inflexible; whereas, one glimpse of the moral and spiritual glory of God, and supreme amiableness of Jesus Christ, shining into the heart, overcomes and abolishes this opposition, and inclines the soul to Christ, as it were, by an omnipotent power.
