What do we mean by the World?
“The world is the general name for all the passions. When we wish to call the passions by a common name, we call them the world. But when we wish to distinguish them by their special names, we call them the passions. The passions are the following: love of riches, desire for possessions, bodily pleasure from which comes sexual passion, love of honour which gives rise to envy, lust for power, arrogance and pride of position, the craving to adorn oneself with luxurious clothes and vain ornaments, the itch for human glory which is a source of rancour and resentment, and physical fear. Where these passions cease to be active, there the world is dead; for though living in the flesh, they did not live for the flesh. See for which of these passions you are alive. Then you will know how far you are alive to the world, and how far you are dead to it”
‑ St. Isaac the Syrian
The Bible clearly tells us to put death all worldly passions. And it does give robust reasons for this. Let’s read Colossians 3:5-11 which says:
5 Put to death therefore what is earthly in you: sexual immorality, impurity, passion, evil desire, and covetousness, which is idolatry. 6 On account of these the wrath of God is coming. 7 In these you too once walked, when you were living in them. 8 But now you must put them all away: anger, wrath, malice, slander, and obscene talk from your mouth. 9 Do not lie to one another, seeing that you have put off the old self with its practices 10 and have put on the new self, which is being renewed in knowledge after the image of its creator. 11 Here there is not Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave, free; but Christ is all, and in all.
