Oh boy. You haven't given one verse that says someone can't believe until they are born of the spirit..
I did give verses, but perhaps you haven't been fully reading my posts. Here they are again from post 55,
43 Why do ye not understand my speech? even because
ye cannot hear my word." (John 8:43)
47 He that is of God heareth God's words (notice the one hearing is already of God): ye therefore hear them not,
because ye are not of God. (John 8:47)
26 But ye believe not,
because ye are not of my sheep, as I said unto you. (John 10:26)
18 For the
preaching of the cross is
to them that perish foolishness" (1 Corinthians 1:18A)
Certainly not mentioned here:
John 3:18 Whoever believes in him is not condemned, but whoever does not believe stands condemned already because they have not believed in the name of God’s one and only Son.
John 3:36 Whoever believes in the Son has eternal life, but whoever rejects the Son will not see life, for God’s wrath remains on them.
The first verse you gave above (John 3:18) the word "believes" is in present tense. It does not say "whoever will believe in him is not condemned", but, "whoever believes", thus the person believing is already born again and your theory not proved.
The next verse you gave (John 3:36) also has the word "believes" in the present tense and states such an individual is already possessing "eternal life". It clearly states, "Whoever believes in the Son
has eternal life" it does not say "whoever will believe in the Son will get eternal life". As for the last part of that verse, the version you used (I do not know what version it is) states, " but whoever rejects the Son will not see life," however the King James version (which is the closest version to the literal Greek original language) renders it, "and he that believeth not the Son shall not see life". This translation is a totally different meaning. You cannot "reject" something that was never offered, thus I really take issue with the translators of whatever paraphrased version it is you are using.
Finally, notice the last part of the verse you provided states in your version, "...for God’s wrath remains on them", does God's wrath remain on those he loves? Of course not, thus this verse proves God does not love every human being, but rather only the sheep not the Goats. "I pray for them: I pray not for the world, but for them which thou hast given me; for they are thine" (John 17:9)
