Contradiction with Matthew 3:9
Suggests that being descendants of Abraham does not automatically make one righteous or entitled to God's promises, contrary to John 8:37's acknowledgment of Abrahamic descent.
Matthew 3:9: And think not to say within yourselves, We have Abraham to [our] father: for I say unto you, that God is able of these stones to raise up children unto Abraham.
Contradiction with John 8:39
Contest the claim by emphasizing actions over mere ancestry, indicating true children of Abraham would emulate his deeds, differing from the implication of John 8:37.
John 8:39: 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.
Contradiction with Romans 9:7
States that not all descendants of Abraham are considered his children in the context of God's promise, contradicting the assumption in John 8:37 that lineage is significant.
Romans 9:7: Neither, because they are the seed of Abraham, [are they] all children: but, In Isaac shall thy seed be called.
Contradiction with Galatians 3:7
Argues that those who have faith are true children of Abraham, opposing the focus on physical descent in John 8:37.
Galatians 3:7: Know ye therefore that they which are of faith, the same are the children of Abraham.
