1 Cor 2:14 shows us that the natural man has no spiritual capacity to receive and understand the Gospel.
God never hid the gospel. The gospel is revealed in Scripture from Genesis to Revelation.
The hidden wisdom was hid from ages and from generations (Col 1:26).
Getting back to what is written in John 3, the Lord Jesus Christ makes clear that the reason Nicodemus did not know these things (vs 10) was because he did not receive [lambanō] the witness:
John 3:11 Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness.
Jesus makes clear that it was not because Nicodemus could not hear or that Nicodemus could not understand ... but because Nicodemus did not receive our witness.
The word "receive" is translated from the Greek word lambanō which means:
"actively lay hold of to take or receive," see NAS dictionary) – properly, to lay hold by aggressively (actively)accepting what is available (offered). 2983/lambánō ("accept with initiative") emphasizes the volition (assertiveness) of the receiver.

... and I know you will not receive the witness because your erroneous dogma requires that one must be regenerated (born again) before he/she can hear. Well that information is not included in the record in John 3 so you're going to have to find another record in Scripture to support your claim.
