Behold, how great a love the Father has bestowed on us, that we should be called children of God! For this cause the world doesn't know us, because it didn't know him.
because it knew him not; neither the Father, whose sons they are, and who has bestowed the grace upon them; wherefore they know not, and disown and persecute his children; see John 17:25; nor the Lord Jesus Christ, the only begotten of the Father, the firstborn among many brethren; who, though he made the world, and was in it, was not known by it, but was hated, abused, and persecuted; and therefore it need not seem strange that the saints, who are the sons of God by adoption, should be treated in like manner.
