Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him. 1 John 2:15 KJV
Love not. He had said before that the only rule for living religiously, is to love God; but as, when we are occupied with the vain love of the world, we turn away all our thoughts and affections another way, this vanity must first be torn away from us, in order that the love of God may reign within us. Until our minds are cleansed, the former doctrine may be iterated a hundred times, but with no effect: it would be like pouring water on a ball; you can gather, no, not a drop, because there is no empty place to retain water.
