Strange thing for Deedat to say. The Quran states that Mary was a virgin when Jesus was conceived and born but gives no explanation of how Jesus was conceived. Christians of course know that it was by the Holy Spirit coming upon Mary. In some ways similar to the creation of Adam. God’s Spirit was breathed into Mary and she conceived but this time the life was that of the Son of God.

Deedat seems to be suggesting that the Bible is implying that God had sex with Mary and Sarah. This is of course a blasphemous thing to say. With Sarah the father of Isaac was Abraham and the Holy Spirit’s work there was to enable Sarah to be able to conceive, probably by healing whatever was the health problem.
