The Muslim claim that Jesus’ virgin birth was simply a miracle to show God’s power doesn’t work if only Mary could know about it.
When people question the reasoning for Jesus being created by God through a virgin birth in Islam since he isn’t viewed as God’s son in that religion, Muslims generally say it was meant to be a miracle to show how powerful God is, with the capability of doing anything. So he did that instead of choosing a man who was already alive to be his next prophet.
However, this argument has some problems, namely the fact that if it was simply meant to be a miracle, it isn’t one that could be verified by anybody.
It isn’t an obvious visible miracle that anybody could see and not have any natural explanation for. Mary simply becomes pregnant without a biological father being involved. If she had gone around saying that nobody would have any reason to believe it and would just assume her husband Joseph was the father.
The bible even states that they claimed Joseph was Jesus’ father and kept the actual circumstances to themselves. Even Joseph couldn’t be 100% sure that Mary didn’t secretly have an affair with another man if it wasn’t for angels telling him.
Basically the only person that could be 100% sure it was a miracle is Mary herself since she knows she didn’t have sex with a man. It isn’t really a miracle to show God’s power if nobody can see it or verify it. It’s not like the sea being split in Exodus, which had thousands of witnesses who could confirm it since it was an obvious visible event and actually made them realize an all-powerful being existed.
If some woman came around today in 2026 saying she got pregnant despite being a virgin, nobody would believe her. If we saw a sea or ocean being split today, tons of people would witness it and would take recordings and many atheists would start believing in God.
The claim that it was for God to show his power doesn’t work if nobody can actually see the miracle being performed.
