jml:
When used in passages referring to salvation, "world" almost always means every single individual without exception
No it does not. It normally means in that context, the gentiles..One of the biggest problems in Christ day and the apostles is that salvation was only for the jews, so there was always a strong emphasis on the world..to stress the scope of God's redeeming love being beyond the ethnic jewish state..hence Jn 3:
16For
God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
And as stated the word world denotes any gathering of particulars to form a whole.
The word is kosmos :
) an apt and harmonious arrangement or constitution, order, government
2) ornament, decoration, adornment, i.e. the arrangement of the stars, 'the heavenly hosts', as the ornament of the heavens. 1 Pet. 3:3
3) the world, the universe
4) the circle of the earth, the earth
5) the inhabitants of the earth, men, the human family
6) the ungodly multitude; the whole mass of men alienated from God, and therefore hostile to the cause of Christ
7) world affairs, the aggregate of things earthly
a) the whole circle of earthly goods, endowments riches, advantages, pleasures, etc, which although hollow and frail and fleeting, stir desire, seduce from God and are obstacles to the cause of Christ
8)
any aggregate or general collection of particulars of any sort
a)
the Gentiles as contrasted to the Jews (Rom. 11:12 etc)
Now that word aggregate is defined by our english dictionary as:
a noun:
A total considered with reference to its constituent parts;
a verb:
To gather into a mass, sum, or whole.
And so,
the Gathering in of God's Sheep from amongst the world constitutes a world..
Jesus speaking of His Sheep in the gentile world, says this Jn 10:
16And other sheep I have, which are not of this fold: them also
I must bring or gather, and they shall hear my voice;
and there shall be one fold, and one shepherd.
This One fold is actually a World.. And thats the World He layed down His Life for, the World of His Sheep Jn 10:
15As the Father knoweth me, even so know I the Father:
and I lay down my life for the sheep.
So technically, Sheep and World are the same in the purpose of salvation..
