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."

Dopamine is the drug of choice for those that are of the world (only of Nature). See the issue All that is of the world for an explanation.

Karl Marx: "Sense experience must be the basis of all science." "Science is only genuine science when it proceeds from sense experience, in the two forms of sense perception and sensuous need, that is, only when it proceeds from Nature."

All Karl Marx did (using the so called "scientific method" to defining and establishing behavior) was make "the lust of the flesh," "sensuous need, "the lust of the eyes," "sense perception" and "the pride of life," "sense experience," making "all that is in the world," "only" that which "proceeds from Nature" the only ground from which to define and establish behavior, removing God and His Word from having any input in the outcome, replacing unalienable rights with human rights in order for him (and all who follow him) to do wrong, disobey, sin, lust without fearing being judged, condemened, cast out, silencing, censoring, and removing anyone, including the unborn, the elderly, the innocent, the righteous who get in the way of his carnal desires of the moment that the world is stimulating, doing so without having a guilty conscience, with "the people's" affirmation.

The Marxist György Lukács (founder of the "Frankfurt School,") explained what the Marxist had to overcome in order to rule over the world. ". . . the central problem is to change reality . . . reality with its 'obedience to laws.'" (György Lukács, History and Class Consciousness: What is Orthodox Marxism?)

When you reject the Law of God, making behavior subject to human nature only, all you can end up with is the law of the flesh, the law of sin.

Romans 7:7 "I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet."

Peter 2:3 "And through covetousness [finding what you are lusting after] shall they with feigned words [offer to "help" you actualize it] make merchandise of you [turn you into "human resource" in order to "own" you, using you and your children's inheritance to satisfy their lusts]."

Proverbs 16:25 "There is a way that seemeth right unto a man, but the end thereof are the ways of death."

Luke 11:35 "Take heed therefore that the light which is in thee be not darkness."

"And what concord [harmony or agreement] hath Christ with Belial?" 2 Corinthians 6:14-18. "No man can serve two masters:  for either he will hate the one, and love the other. . .Ye cannot serve God and mammon." Matthew 6:24
