John 8:37-40 I know that you are Abraham’s seed; but you seek to kill me, because my word has no place in you. I speak that which I have seen with my Father: and you do that which you have seen with your father. They answered and said unto him, Abraham is our father. Jesus said unto them, If you were Abraham’s children, you would do the works of Abraham. But now you seek to kill me, a man that hath told you the truth, which I have heard of God: this did not Abraham.
‘Abraham is our father’ True, according to the flesh, but this does not make true children of Abraham or true Israelites. One must not only be a descendant in the flesh but must also be saved and a child of the promise to be a true Jew and an Israelite (Rom. 2:28-29; 9:4-11). If they (the Jews) were really the spiritual seed of Abraham they would imitate him in faith, obedience, and righteousness; but they seek to kill Jesus merely because He told them the truth; Abraham never did anything like this.
The only place Jesus calls Himself a “man” (v 40) He generally refers to Himself as the ‘Son of God’ and ‘Son of Man’ (John 1:49, 51). He was truly man and truly God in nature, being born of God and a virgin (Matt. 1:18).
There were ten reasons why the Jews killed Jesus: His Kingship (Matt. 2:2-3, 16; John 18:33-40; 19:12-22); for telling the truth (Luke 4:21-29; John 8:40); for healing on the sabbath (Matt. 12:9-14; Mark 3:1-6; John 5:16; 9:16); for claiming Sonship (John 5:18; 10:24-39; 19:7); and for claiming to be God (John 8:53-59; 10:33); they were jealous of Him (Matt. 26:3-4; 27:18; Mark 14:1; 15:10; Luke 22:2; John 11:48); they were ignorant (Matt. 26:64-66; Mark 14:62-64; John 12:40; Acts 3:17); for fear of losing their authority (John 11:46-53; 12:10-11, 19); for their unbelief (John 5:38-47; 6:36; 9:40-41; 12:36-38); they killed Him to fulfill prophecy (Luke 13:33-35; John 12:38-40; 18:31-32; 19:11, 28, 36-37; Acts 2:22-36; 3:18).
