18 Now the birth of Jesus Christ was as follows: when His mother Mary had been betrothed to Joseph, before they came together she was found to be with child by the Holy Spirit.
19 And Joseph her husband, being a righteous man and not wanting to disgrace her, planned to send her away secretly.
20 But when he had considered this, behold, an angel of the Lord appeared to him in a dream, saying, “Joseph, son of David, do not be afraid to take Mary as your wife; for the One who has been conceived in her is of the Holy Spirit.
21 “And she will bear a Son; and you shall call His name Jesus, for He will save His people from their sins.”
22 Now all this took place in order that what was spoken by the Lord through the prophet would be fulfilled, saying,
23 “BEHOLD, THE VIRGIN SHALL BE WITH CHILD AND SHALL BEAR A SON, AND THEY SHALL CALL HIS NAME IMMANUEL,” which translated means, “GOD WITH US.”
24 And Joseph got up from his sleep and did as the angel of the Lord commanded him, and took Mary as his wife,
25 but kept her a virgin until she gave birth to a Son; and he called His name Jesus.
“These are very mysterious subjects. We cannot fathom these depths. They are truths which are beyond our understanding. Let us not attempt to explain things which are above our feeble reason. Let us be content to believe with reverence, and let us not speculate about matters which we cannot understand. It is enough for us to know that with Him who made the world nothing is impossible.” (J.C. Ryle D.D.)
“A skeptic who denied the virgin birth once asked a Christian, ‘If I told you that child over there was born without a human father would you believe me?’ The believer replied, ‘Yes, if he lived as Jesus lived.’ The greatest outward evidence of Jesus’ supernatural birth and deity is His life.” (Dr. John MacArthur)
