37 I am conscious that you are Abraham's seed; but you have a desire to put me to death because my word has no place in you.
38 I say the things which I have seen in my Father's house: and you do the things which come to you from your father's house.
39 In answer they said to him, Our father is Abraham. Jesus said to them, If you were Abraham's children you would do what Abraham did. 40 But now you have a desire to put me to death, a man who has said to you what is true, as I had it from God: Abraham did not do that.
Matthew Henry's Commentary on John 8:37-40
Commentary on John 8:37-40
(Read John 8:37-40)
Our Lord opposed the proud and vain confidence of these Jews, showing that their descent from Abraham could not profit those of a contrary spirit to him. Where the word of God has no place, no good is to be expected; room is left there for all wickedness. A sick person who turns from his physician, and will take neither remedies nor food, is past hope of recovery. The truth both heals and nourishes the hearts of those who receive it. The truth taught by philosophers has not this power and effect, but only the truth of God. Those who claim the privileges of Abraham, must do Abraham's works; must be strangers and sojourners in this world; keep up the worship of God in their families, and always walk before God.
