The word world !
The false teachers are going to be guilty of slothfulness like the unprofitable servant Matt 25:13-40
14 For the kingdom of heaven is as a man travelling into a far country, who called his own servants, and delivered unto them his goods.
15 And unto one he gave five talents, to another two, and to another one; to every man according to his several ability; and straightway took his journey.
16 Then he that had received the five talents went and traded with the same, and made them other five talents.
17 And likewise he that had received two, he also gained other two.
18 But he that had received one went and digged in the earth, and hid his lord's money.
19 After a long time the lord of those servants cometh, and reckoneth with them.
20 And so he that had received five talents came and brought other five talents, saying, Lord, thou deliveredst unto me five talents: behold, I have gained beside them five talents more.
21 His lord said unto him, Well done, thou good and faithful servant: thou hast been faithful over a few things, I will make thee ruler over many things: enter thou into the joy of thy lord.
22 He also that had received two talents came and said, Lord, thou deliveredst unto me two talents: behold, I have gained two other talents beside them.
23 His lord said unto him, Well done, good and faithful servant; thou hast been faithful over a few things, I will make thee ruler over many things: enter thou into the joy of thy lord.
24 Then he which had received the one talent came and said, Lord, I knew thee that thou art an hard man, reaping where thou hast not sown, and gathering where thou hast not strawed:
25 And I was afraid, and went and hid thy talent in the earth: lo, there thou hast that is thine.
26 His lord answered and said unto him, Thou wicked and slothful servant, thou knewest that I reap where I sowed not, and gather where I have not strawed:
27 Thou oughtest therefore to have put my money to the exchangers, and then at my coming I should have received mine own with usury.
28 Take therefore the talent from him, and give it unto him which hath ten talents.
29 For unto every one that hath shall be given, and he shall have abundance: but from him that hath not shall be taken away even that which he hath.
30 And cast ye the unprofitable servant into outer darkness: there shall be weeping and gnashing of teeth.
This applys to the use of the word world in the scripture, the word kosmos, and how its used in scripture, the majority of the time in a limited, restricted sense, wherein it doesnt mean all mankind without exception, yet false teachers slothfully insist that it does ! Lets look at Jn 12:19
19 The Pharisees therefore said among themselves, Perceive ye how ye prevail nothing?
behold, the world/Kosmos is gone after him.
Now who in their right mind would say that world here means all mankind without exception ?
For there were indeed at that very time many who did go after Jesus, so the world kosmos must be understood in a Limited sense, a restricted sense, in fact some versions like the vulgate latin, Syriac, Arabic and Ethiopic would read " The whole world " See also the NIV
19 So the Pharisees said to one another, “See, this is getting us nowhere. Look how
the whole world has gone after him!”
The DRB:
19 The Pharisees therefore said among themselves: Do you see that we prevail nothing?
behold, the whole world is gone after him.
Lets look also at the phrase in 1 Jn 5:19
19 We know that we are of God, and
the whole world is seated in wickedness.
The whole world lieth in wickedness "ho Kosmos holos" and even here the whole world is limited/ restricted to the unsaved , unredeemed populos, it cannot by no means include the redeemed believers in Jesus Christ, wherein John had just said to them, to include himself "
We know that we are of God"
So if the phrase the whole world is used in a limited restrictive sense in 1 Jn 5:19, marvel not that its used that way in 1 Jn 2:2
And he is the propitiation for our sins: and not for ours only,
but also for the sins of the whole world.
So whereas in 1 Jn 5:19 the redeemed ones are the obvious exception, so it is in 1 Jn 2:2 the unredeemed sinners and unbelievers are the exception !
