John 3:16
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.
(Joh 3:16)
Well let's look at that context:
Joh 3:14 And as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up,
Joh 3:15 that whoever believes in him may have eternal life.
First He references the bronze serpent in the wilderness :
Num 21:8 And the LORD said to Moses, "Make a fiery serpent and set it on a pole, and everyone who is bitten, when he sees it, shall live."
Num 21:9 So Moses made a bronze serpent and set it on a pole. And if a serpent bit anyone, he would look at the bronze serpent and live.
So the passage is in fact not only just a lesson about how much God loves, but the dynamics of God's plan to save people
The serpent was lifted up and those who looked to it were saved. Christ would be lifted up and whoever believes in Him will have eternal life.
Now that He has indicated that it is looking on the Son in belief that saves He shows the scope of this:
Joh 3:16 "For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.
The terms whoever are not ambiguous. The term world does indeed take Nicodemus beyond his possible prejudices, to include not just gentiles, but even the lowly people he might consider sinners among the Israelites. That is the point....all the world. God loves them all. God offers the chance for all to look to His Son and be saved.
Joh 3:17 For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him.
Joh 3:18 Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God.
Now surely the Calvinist would agree He is speaking of the whole world when it talks about those who do not believe and are already condemned. Surely you believe that extended to every person. But it is the same world that is being offered salvation. The offer of salvation extends as far as the description of the already condemned.
No where did Christ limit who He was talking about here. The whole world started out condemned by sin, and the whole world was giving a choice to look to the Son and believe, and be saved.
Also, Jesus makes a subtle appeal to Nicodemus:
Joh 3:20 For everyone who does wicked things hates the light and does not come to the light, lest his works should be exposed.
Joh 3:21 But whoever does what is true comes to the light, so that it may be clearly seen that his works have been carried out in God."
Nicodemus came to Jesus at night. It was not until he saw Jesus lifted up that He came into the light and took his stand for Christ while even the disciples were running scared.
Apparently He thought that Nicodemus had a choice to make, because he was one of the people of the world.
