And the angel said unto her, Fear not, Mary: for thou hast found favour with God. And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name JESUS. He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David. And he shall reign over the house of Jacob for ever, and of his kingdom there shall be no end.
For with God nothing shall be impossible.
Luke 1:30-33, 37
