﴿ قَالَتْ رَبِّ أَنَّىٰ يَكُونُ لِى وَلَدٌۭ وَلَمْ يَمْسَسْنِى بَشَرٌۭ ۖ قَالَ كَذَٰلِكِ ٱللَّهُ يَخْلُقُ مَا يَشَآءُ ۚ إِذَا قَضَىٰٓ أَمْرًۭا فَإِنَّمَا يَقُولُ لَهُۥ كُن فَيَكُونُ ﴾

“Said she: "O my Sustainer! How can I have a son when no man has ever touched me?" [The angel] answered: "Thus it is: God creates what He wills when He wills a thing to be, He but says unto it, 'Be' - and it is.”

The Jews were chosen by God for the special mission of being the bearers of divine guidance so that, along with following the path of God, they should also communicate this guidance to others. But the rot set in in the Jews in later times. Then a time came when they were no longer worthy of being the bearers of divine guidance. God then took away this trust from them and gave it to the other branch of Abraham’s dynasty, the Banu Isma‘il. Before the enforcement of this decree, it was necessary to prove to them that they were no longer to be trusted. Jesus Christ was sent by God for this purpose. His extraordinary birth and his performance of extraordinary miracles were meant to convince the Jews of his messengership (i.e. that he had been sent by God) and that he was speaking on behalf of God.
