So your view of it remains to be that the term world, in this passage and others, despite of what I have shared, means every single person who ever lived and ever will live. Can you provide evidence of that, especially biblical evidence that contradicts the conclusions I have drawn from Scripture and/or history
Dear RB the context following John 3:16 proves IMO that this is exactly what "kosmos" means every person who has lived or will live
16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.
20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.
21 But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.
17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.
20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.
21 But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.
In the cosmos of the context in successor verses to 3:16 there are two kinds on persons in this kosmos, those who love the light and those who don't.
Again as I mentioned before, it is not John's style to use "cosmos" as the "world" of believers but all of humanity.
Another passage:
John 1
9 That was the true Light, which lighteth every man that cometh into the world.
10 He was in the world, and the world was made by him, and the world knew him not.
11 He came unto his own, and his own received him not.
9 That was the true Light, which lighteth every man that cometh into the world.
10 He was in the world, and the world was made by him, and the world knew him not.
11 He came unto his own, and his own received him not.
Here John indeed contrasts Israel not as different than the world but as the same in their rejection of Him and IMO is including them in the "cosmos" which as periviously shown in John 3 that it is comprised of two kinds of people, those who love the darkness and those who love the light (presumably the elect who are predisposed to this light). To say that John 3 use of the word world is not all inclusive but singling out the world of believers (or elect) makes the entire passage a confusion.
then we also have passages such as Paul gives to a mix of skeptical unbelieving gentiles and those who did hear him:
Acts 17
29 Forasmuch then as we are the offspring of God, we ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man's device.
30 And the times of this ignorance God winked at; but now commandeth all men every where to repent:
31 Because he hath appointed a day, in the which he will judge the world in righteousness by that man whom he hath ordained; whereof he hath given assurance unto all men, in that he hath raised him from the dead.
Acts 17
29 Forasmuch then as we are the offspring of God, we ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man's device.
30 And the times of this ignorance God winked at; but now commandeth all men every where to repent:
31 Because he hath appointed a day, in the which he will judge the world in righteousness by that man whom he hath ordained; whereof he hath given assurance unto all men, in that he hath raised him from the dead.
Here we see Paul preaching that God has commanded all men everywhere to repent claiming that God will judge the world (presumably all who lived and ever will live - granted this is the word "oikomene" and not "kosmos") and has given ALL (same presumption) assurance in that He raised Him (Jesus) from the dead. This being the essential reason why all men everywhere should repent seemingly making God Himself a supporter of a general atonement.
