15 Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. 16 For all that is in the world—the lust of the flesh, the lust of the eyes, and the pride of life—is not of the Father but is of the world. 17 And the world is passing away, and the lust of it; but he who does the will of God abides forever. (1 John 2:15–17, NKJV)
The universe is an arranged system of celestial bodies we call the cosmos. Here, John speaks of another world or “kosmos” – the system of evil that is in opposition to God and His will. This arrangement of evil – the world – consists of the lusts of the flesh, the lust of the eyes and the pride of life (v. 16). The god of this world, the devil, uses these three avenues to deceive and entice souls to their eternal demise. At least one of these three elements is at the heart of every sin and false doctrine that exists. Cleverly disguised as pleasure, success, fulfillment, joy, and self-satisfaction, and many other things, Satan uses them to lure people away from God. The world offers a counterfeit love. We must love God genuinely. That means we must not love the world. It is fading away, but life everlasting is for those who do the will of God.
