1) The Greek word translated by your translation version is "pas" and the KJV translates it as "everyone" 28 times. Either you do not know what you are talking about, or you are deliberately posting falsehood.Whoever does not mean "everyone" and you should know better than this! It is a qualifying statement characterizing and distinguishing one group from the other.
1. WHOEVER has a ticket may enter the stadium (may board the train, enter the airport terminal, etc.).
2. It does not mean EVERYONE may enter. It means everyone WHO HAS A TICKET may enter. Everyone who DOES NOT have a ticket may not enter.
3. It should be quite clear to all that one MUST HAVE a ticket in order to enter.
Jn 3:17 is quite clear about this just in case you have not yet fully understood what 3:16 means:
He that BELIEVETH ON HIM (has a ticket) is not condemned: but he that BELIEVETH NOT (does not have a ticket) is condemned already, because he hath not believed in the name of the only begotten Son of God.
The underlying Greek is πᾶς πιστεύω (pas pisteuo), literally meaning: "all believing" which is translated as either whosoever believes, whoever believes, all who believe, or everyone who believes. Pretty simple and straightforward here.
A Calvinist does not have to read into the passage saying "Whoever the elect are" shall believe in him. It may be implied by all that all who believe ARE the elect.
An Arminian MAY NOT read into the passage "EVERYONE MAY BELIEVE and be saved" as the text simply does not say this. Perhaps they may or perhaps they may not. The passage simply says "All who believe are saved."
2) The classification criteria of "pas" is everyone who believes into Him. The ticket is supplied by God when and if He credits the person's faith in Christ as righteousness, and then transfers that individual into Christ. Thus they "believed into Him.
3) See #2.
4) Sorry but your translation of John 3:18 says "believes on Him, but the Greek reads "believes into (eis) Him. "On" is a different preposition, "epi."
5) Totally false claim. "all that believe into Him" is what the verse says.
6) You demonstrated by your post that you are simply posting your indoctrinated but false views.
I see no need to continue.
