Our love is like ourselves; as we are, so are all our affections: so is the love of Christ like himself. We love one, one day, and hate him the next. He changeth, and we change also: this day he is our right hand, our right eye; the next day, “Cut him off, pluck him out.” Jesus Christ is still the same; and so is his love. “In the beginning he laid the foundation of the earth; and the heavens are the works of his hands; they shall perish, but he remaineth: they all shall wax old as doth a garment; and as a vesture shall he fold them up, and they shall be changed: but he is the same, and his years fail not,” Heb. 1:10-12. He is the Lord, and he changeth not; and therefore we are not consumed. Whom he loves, he loves unto the end. His love is such as never had beginning, and never shall have ending.
