The most famous verse in the Bible is John 3:16 LITV, For God so loved the world that He gave His only begotten Son, that everyone believing into Him should not perish, but have everlasting life.
The word "world" here does not refer to everyone, but the word "world" refers to the world of men from every tribe, nation, tongue and people.
Let is look In v. 14 first: Jesus speaks about when Moses made a bronze serpent and set it on a pole.
The children of Israel were disobedient to God and the Lord sent fiery serpents among the people, and many of the people of Israel died.
Then the people of Israel repented, and God commanded Moses to make a fiery serpent, and set it on a pole, and anyone who gets bitten by a fiery serpent, when he looks at the serpent which Moses made, will live.
Moses did what the Lord commanded him, and made a fiery serpent made of bronze, and put it on a pole, and everyone bitten and looked upon the serpent of bronze, he lived.
Jesus is telling Nicodemus as this happened for Israel, I will do for the whole world, the whole world of men, from every tribe, nation, tongue and people.
Nicodemus and other Jews believed a Saviour, a promised Messiah was coming but they believed the Saviour was coming for the Jews, but the Lord Jesus is telling Nicodemus, I am not coming for the Jews only, but for Jews and Gentiles, the whole world of men from every tribe, nation, language, and people. That is what the word "world" means in the context it is used.
Jesus died for His sheep from every tribe, nation, language and people.
The Bible says in John 10:11LITV
I am the Good Shepherd! The Good Shepherd lays down His life for the sheep.
