The essence of love is spiritual, coming from God's Presence in us, for God is love, and love is of God, and the fruit of the Spirit is love. Love exists in 4 dimensions - the length, height, depth and width. We must (1) receive His love into our heart by faith, so we are filled with His love (Ephesians 3:14-19), then (2) release His love by our words and actions.
