40 "So now, proceed in seeking to kill Me! (or: Yet now you are continually seeking to kill Me; [note: the verb "seeking" is either present imperative or present indicative]) – a Man (person; human) Who has spoken to you the truth which I hear from (or: heard at) God's side (or: in the presence of God). Abraham does not do this (or: did not do this).
41 "You folks habitually do your father's works (deeds; actions)." Therefore they said to Him, "We ourselves were not born out of prostitution (or: fornication). We have one Father: God!"
42 Jesus said to them, "If God were your Father, you folks would have been, and continued, loving Me, for I Myself came forth and am arrived here (or: and here I am) from out of the midst of God. For neither have I come from Myself (= on My own initiative), but rather that One sent Me away with a mission (commissions and sends Me forth as an Emissary, [His] Representative).
43 "How (Through what [situation]) is it that you folks consistently do not understand (have personal, experiential knowledge of) the matter of My discourse or the way I’m speaking (= Why don't you understand what I'm saying)? Because you have no power (are unable) to continue hearing My word (or: to repeatedly or progressively listen to My message, thought or idea).
44 "You folks, in particular, are (exist and have your being) from out of, and have your source in, the ancestor who cast [an object] through [someone] (or: the father, the devil; or: the devil father; or: the father – the one thrusting [words or issues] through [folks/groups] and dividing them), and you are habitually wanting (willing; intending; purposing) to be constantly doing your father's passionate cravings (full-rushing over-desires). That one was existing being a murderer (a killer of humanity) from [his/its] beginning (or: from [the] start; from [its] origin; or: from headship, chieftainhood, government or rule), and he/it has not stood and does not now stand within the Truth (or: it had not made a stand in union with reality), because truth is not (openness and reality does not exist) within him (or: it). Whenever he/it may be speaking the lie, he/it is continuing speaking from out of his own things – because he/it is (or: continues existing being) a liar, and its father [note: either the father of the lie, or of the liar].
