There is a judge for the one who rejects me and does not accept my words; that very word which I spoke will condemn him at the last day.
“rejects” = The Greek word is atheteo which means to reject or despise. This is a very strong word and Barclay translates it as, “He who completely disregards me as of no account.” (Luke 10:16)
Luke 10:16 “He who listens to you listens to me; he who rejects you rejects me; but he who rejects me rejects him who sent me.”
The judgment for the one who has rejected Christ will be that the word of salvation came to him and he completely disregarded it.
