Henry Alford packs more meaning into a single sentence than most Bible commentators do in several paragraphs. I always enjoy reading his commentary because he is so succinct and deep.
A couple of examples from our passage. Alford thinks through the meaning of these two verses:
“You are of your father the Devil, and you want to carry out your father’s desires. He was a murderer from the beginning and has not stood in the truth, because there is no truth in him. When he tells a lie, he speaks from his own nature, because he is a liar and the father of liars.” (John 8:44 HCSB)
“I assure you: If anyone keeps My word, he will never see death—ever!”” (John 8:51 HCSB)
Alford comments: “Ye are now children of the devil, but if ye keep My word, ye shall be rescued from that murderer.”
““If I glorify Myself,” Jesus answered, “My glory is nothing. My Father—you say about Him, ‘He is our God’—He is the One who glorifies Me. You’ve never known Him, but I know Him. If I were to say I don’t know Him, I would be a liar like you. But I do know Him, and I keep His word.” (John 8:54–55 HCSB)
Alford: “The sense is, of Whom ye say ‘He is our God,’ and (not “yet” nor “but”) know Him not. Then what follows sets forth the contrast between them, the pretended children of Abraham, who know not Abraham’s God (the liars), and Him who knows Him, and keeps His word, so that His word works in and by Him; yea, He is the Word of God. His allowing their denial of this state of knowledge and union would be as great a lie in Him, as their assumption of it was in them.”
Do you see what I mean about Mr. Alford?
