John 8
43 Why do ye not understand my speech? even because ye cannot hear my word.
44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
45 And because I tell you the truth, ye believe me not.
Jesus refers to his "word" (truth). And confirms it in 45. The word "devil" is "against God", or in this case "true God" which Jesus was teaching (glorifying).
The Hebrews never had the Spirit of Truth, never. And in John 8 Jesus says that he is telling them the truth that he hears from his Father, truth that Abraham did not (hear).
38 I speak that which I have seen with my Father: and ye do that which ye have seen with your father.
39 They answered and said unto him, Abraham is our father. Jesus saith unto them, If ye were Abraham's children, ye would do the works of Abraham.
40 But now ye seek to kill me, a man that hath told you the truth, which I have heard of God: this did not Abraham.
41 Ye do the deeds of your father. Then said they to him, We be not born of fornication; we have one Father, even God.
42 Jesus said unto them, If God were your Father, ye would love me: for I proceeded forth and came from God; neither came I of myself, but he sent me.
Until the Spirit of the Father could live within man, it merely influenced.
(But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet given; because that Jesus was not yet glorified.)- John 7
The Hebrews never had the Holy Spirit, the Spirit of Truth. So how could they be led........directly by God? It is a view that takes great prayer to see. The non Canon books follow the Gospel and explain what we miss when we try to go back before Christ to obtain truth.
As far as interpretations, there are many. Read many myself. They can differ depending on who interpretates. One must ask the Spirit to reveal truth, and it will. Not always the first time, or in a matter we suggest. We must be "open" to truth. The Father` will not lie to us, but will let us believe a lie if we so choose. The path is not as easy as one would believe. I was an Orthodox believer for 35+ years. When the spiritual mind opens, it is a dramatic experience of the soul, and everything seems to make "better" sense, at least in my case.
