Some of the events which surround the life of Jesus do take a lot of believing, particularly for a doctor. When I first got to know Paul, I was amazed that he believed in miracles. But it is no use criticizing from afar, you need to go and see for yourself before you can judge fairly, and that is what I did with Paul. I can vouch for many of the miracles he did because I was there. As you read my account of his travels, you will see that in many places I said "we" did this or that.
Of course, I could not go back to the time when Jesus was born and see all those events for myself, but I had seen enough to know that, when God is at work, remarkable things happen. What I did do was to check very carefully the stories I heard. When I was in Jerusalem with Paul, I found Mary was still there (Author's note: John took Mary to safety in Ephesus about 2 years before Jerusalem was destroyed in 70 AD). I was able to question Mary about the stories I had heard from others.
They were vouched for by everyone whom I could trust to give me an honest opinion, even James the brother of Jesus and Mary's second son. These people were men and women who would not lie, so I just had to believe them.
There are other reasons, however, although they are not so straightforward. For one thing, the prophet Isaiah prophesied it. In Chapter 7 verse 14, he declares, "A virgin shall be with child and will bear a son, and shall call Him Immanuel". Immanuel means "God with us". We know that Jesus was Immanuel. Which is more unbelievable, that God should become a man or that He should be born of a virgin? If the prophet was speaking on behalf of God his words are true.
Does it matter whether Jesus was born of a virgin or not? Many people say it does not. They say that His sacrificial death is much more important, and I have to agree with them there. Yet if we can understand His death as the spiritual fulfilment of the Jewish ideas of sacrifice, we must conclude that if the sacrificial goat or bull had to be without physical fault, then Jesus also had to be without spiritual fault - that is, He had to be sinless. Otherwise His sacrifice would have been a waste of time.
Now those of us who have had that life-changing experience we call "being saved" or "being born again", know our sins are forgiven, know that Jesus' sacrificial death was not a waste of time - so Jesus was without sin. I have never come across a normal person, born in the normal way, who was without sin, so there must have been something different about Jesus. The only way I can explain it is that God was His Father. He could not inherit sin from His Father, only perfection, and this overcame any sin He might have inherited from His mother. Which leads us logically to the Virgin Birth.
Do you still find it difficult to believe? Then do not worry about it, rather pray about it. Ask the Holy Spirit to guide you into the truth, then put the matter on one side until He answers.
