John 8:41

The Jews rejected Jesus’ claim that they were not genuine children of Abraham. Their reference to fornication may have been a slur on Jesus’ physical paternity. Who was He with His questionable pedigree to deny their ancestry? They then claimed that on the spiritual level God was their father (Exodus 4:22; Deuteronomy 14:1-2). They apparently believed that Jesus surely could not deny that, though He disputed their connection to Abraham.
