You seem to be misunderstanding John 3:16... which is tied to John 17:9.
Isaiah 24:1-18 [4] The earth mourns and the world is ruined, the lofty ones of the earth are mourning.[5] And she has sinned by reason of her inhabitants, because they have transgressed the Law and changed the Ordinances, even the Everlasting Covenant.[6] Therefore a curse shall consume the earth, because the inhabitants thereof have sinned: therefore the dwellers in the earth shall be poor, and few men shall be left.LXX
Deuteronomy 28:43-52 [43] The proselyte who is among you shall ascend over you upward and upward; but you shall go down lower and lower.[44] This one shall lend to you, but you to this one shall not lend; this one will be for the head, and you will be for the tail.[45] And shall come upon you all these curses, and they shall pursue you, and overtake you, until whenever they shall utterly destroy you, and until whenever they shall consume you. For you did not listen to the voice of the lord your God, to guard His Commandments, and His Ordinances, as many as I gave charge to you.[46] And [they] will be for signs to you, and miracles, and among your seed until the eon.[47] Because you did not serve [the] LORD your God with gladness, and with a good heart, because of the multitude of all these.[48] And you shalt serve your enemies whom the LORD shall send as a successor over you in hunger, and in thirst, and in nakedness, and in the want of all things. And he shall put a collar of iron upon your neck, until whenever he should utterly destroy you.[49] Shall bring upon you [the] LORD a nation far off from [the] end of the earth, as the impulse an eagle, a nation of which you will not hear its voice;[50] a nation impudent in [its] face, who will not admire [the] face of an old man, and for [the] young will not show mercy.[51] And it will devour the progeny of your cattle, and the produce of your land, so as not to leave behind for you grain, wine, olive oil, herds of your oxen, and the flocks of your sheep, until whenever it should destroy you,[52] and should obliterate you in all your cities, until whenever should be demolished your walls--the high and the fortified [ones] upon which you rely upon them in all your land--and it shall afflict you in all your cities, which gave to you [the] LORD your God.
These endtimes (found in Daniel) will happen, because of all this, to the whole world... into which the House of Israel has been scattered.
I'm not able to connect your dots. John 3:16, as far as I can see, shouts salvation by faith loud and clear.
Deuteronomy 28:43-52 is still valid, and it is prophecy found in Daniel. And Isaiah 24:1-18 is in the Revelation. These things will happen because
those who are genetic Israel are only Israel because they were given the Everlasting Covenant and told to keep their part of this Covenant. If they cease being Israel by means of this Covenant, then the world will rock on its axis. The whole world will be punished because they didn't take seriously the warnings of Prophet Moses.
Definition
kosmos = orderly arrangement, i.e. decoration; by implication, the world (
in a wide or narrow sense, including its inhabitants, literally or figuratively (morally)):--adorning,
world.
Is John 3:16 the wide or the narrow definition of "world"?
John 3:16-17 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.
Because
this "love" is conditional, in this Gospel. It requires a man to prove that he loves Ιησους by keeping His Commandments, THEN and only then, the Father will love him. This is how the Holy Spirit is given in this Gospel:
John 14:21-24
He that hath My Commandments and keepeth them, he it is that loveth Me; and he that loveth Me shall be loved of My Father and I will love him, and will manifest Myself to him.[22] Judas saith unto Him, not Iscariot,
Lord, how is it that Thou wilt manifest Thyself unto us, and not unto the world?[23]
Ιησους answered and said unto him, If a man love Me he will keep My words and My Father will love him, and We will come unto him and make Our abode with him.[24] He that loveth Me not keepeth not My sayings; and the word which ye hear is not Mine, but the Father's which sent Me.
Ιησους half-brothers are "of the world":
John 7:5-7 The
world cannot hate you; but Me it hateth, because I testify of it that
the works thereof are evil.
John 17:6-9 "I have manifested Thy name unto the men which Thou gavest Me out of the world. ...[9] I pray for them:
I pray not for the world, but for them which Thou hast given Me; for they are Thine.
John 15:19
If ye were of the world, the world would love his own: but because ye are not of the world, but I have chosen you out of the world, therefore the world hateth you.
John 17:14 I have given them thy word; and
the world hath hated them, because they are not of the world, even as I am not of the world.
Not "of the world".
James 4:4 Ye adulterers and adulteresses, know ye not that the friendship of the world is enmity with God? whosoever therefore will be
a friend of the world is the enemy of God.
The world (people) will be judged by this:
Deuteronomy 18:18-19 I will raise up to them a prophet of their brethren like thee, and
I will put My words in His mouth and He shall speak to them as I shall Command Him.[19] And whatever man shall not hearken to
whatsoever words that prophet shall speak in My name, I will take vengeance on him.LXX John 12:48-50
John 17:6-8 I have manifested Thy name unto the men which Thou gavest Me out of the world:
Thine they were and Thou gavest them Me and they have kept Thy word.[7] Now they have known that all things whatsoever Thou hast given Me are of Thee.[8] For
I have given unto them the words which Thou gavest Me, and they have received them and have known surely that I came out from Thee, and they have believed that Thou didst send Me.
