You are certainly entitled to your opinion, but Ephesians 5:28 and 5:29 seems to indicate it has nothing to do with children.... but moreso that a husband and wife are to care for and respect each other's bodies as if they were their own flesh. So I would assume that a Christian marriage without children or even without sex (due to injury, illness, whatever) would still produce a spiritual pairing that unites 2 as one.
However, I have never been married so I would be curious to hear more from those who have, especially if their union has not produced children. 🤔
