You either love God or you love the world, but you cannot love both. Matthew 6 tells us that “no man can serve two masters: for he will hate the one, and love the other” Did you notice that love and serving are brought together in that verse? You serve the master that you love. That verse concludes, “ye cannot serve God and mammon.” If you think you can love the things of this world AND truly love God, you are deceiving yourself.
A study of 1 John 2:15-17, "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. For all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world. And the world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever."
