Don't love the world, neither the things that are in the world. If anyone loves the world, the Father's love isn't in him.
Neither the things that are in the world - Referred to in the next verse as “the lust of the flesh, the lust of the eyes, and the pride of life.” This explanation shows what John meant by “the things that are in the world.” He does not say that we are in no sense to love “anything” that is in the material world; that we are to feel no interest in flowers, and streams, and forests, and fountains; that we are to have no admiration for what God has done as the Creator of all things; that we are to cherish no love for any of the inhabitants of the world, our friends and kindred; or that we are to pursue none of the objects of this life in making provision for our families; but that we are not to love the things which are sought merely to pamper the appetite, to please the eye, or to promote pride in living. These are the objects sought by the people of the world; these are not the objects to be sought by the Christian.
