The incarnation expresses the love of God

God’s desire to communicate happiness to the creature entails a willingness to experience loss to the sake of the beloved. It is exceeding congruous for God, a being of infinite goodness and love, to give to the creature the highest sort of expression of love which is expensed for the beloved. Therefore through the mission of the Son, God reveals a love that suffers in behalf of the beloved. Now I can clearly and distinctly conceive how the giving of Christ is the perfect expression of love, as the greatest expense in a lover. For the incarnation expresses the love of God in a way that is exceedingly noble and excellent and agreeable to the glorious perfections of God.
