Passage
Art thou greater than our father Abraham, who died? and the prophets died: whom makest thou thyself?
Art thou greater than our father Abraham, who died? and the prophets died: whom makest thou thyself?
John 8:51 Verily, verily, I say unto you, If a man keep my word, he shall never see death.
John 8:52 The Jews said unto him, Now we know that thou hast a demon. Abraham died, and the prophets; and thou sayest, If a man keep my word, he shall never taste of death.
John 8:53 Art thou greater than our father Abraham, who died? and the prophets died: whom makest thou thyself?
John 8:54 Jesus answered, If I glorify myself, my glory is nothing: it is my Father that glorifieth me; of whom ye say, that he is your God;
John 8:55 and ye have not known him: but I know him; and if I should say, I know him not, I shall be like unto you, a liar: but I know him, and keep his word.
The verse centers on "thou", "greater", "than", "father", "abraham", "died", and "prophets". It is saying that the verse draws attention to "thou" and "greater", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 52's "The Jews said unto him Now we..." into verse 54's "Jesus answered If I glorify myself my...", so "thou" and "greater" belong inside that flow. In John context, the local focus is the identity of Jesus, new birth, eternal life, and belief and unbelief.
A plain takeaway is to answer the verse's own emphasis on "thou" and "greater" with trust shaped by these words, not by a vague optimism outside the passage.
