Jn 3:16 tells us of God's Love for the world, but never specifically states that God loved all mankind as individuals without exception, that has been read into the text by those who care little about the Truth of God.
And such a verse as Jn 3:16
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.
Must and should be explained by other verses of scripture that speaks on the same subject as God's Love of People.
First lets look at at an OT scripture that speaks to God's Love to a People Deut 7:6-8
6For thou art an holy people unto the LORD thy God: the LORD thy God hath chosen thee to be a special people unto himself, above all people that are upon the face of the earth.
7The LORD did not set his love upon you, nor choose you, because ye were more in number than any people; for ye were the fewest of all people:
8But because the LORD loved you, and because he would keep the oath which he had sworn unto your fathers, hath the LORD brought you out with a mighty hand, and redeemed you out of the house of bondmen, from the hand of Pharaoh king of Egypt.
We find here something extremely important about an immutable God and His Love. That God's Love is set upon a people He chooses look at Deut 7:7
7The LORD did not set his love upon you, nor choose you, because ye were more in number than any people; for ye were the fewest of all people:
Notice too that His Love is set upon the fewest of all people.. This should be a big eye opener for us, God Loves not the masses of mankind, for those He Loves are the few of mankind.
Remember Jesus stated about finding the road that leads to life that few find it Matt 7:13-14
13Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat:
14Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.
Those few, are and will be those God Loved.. So God so loved the world, means He loved a few , chosen ones in the world, His own special ones.
Jn 13:1
1Now before the feast of the passover, when Jesus knew that his hour was come that he should depart out of this world unto the Father, having loved his own which were in the world, he loved them unto the end.
The jews would have known from Deut 7 that God's Love was exclusive for only some, but what they did not know was that some was not limited to them, for God loved some as well of different people groups, outside of their race; but His Love was nevertheless limited to a certain people, but just not to a limited location or race, it was the world at large that this special loved and certain people would be located..
