Maybe this is generally true. “Be fruitful and multiply” would indicate that. But there are too many exceptions for me to say things as definitively as you have.

Paul was single and encouraged others to stay the same (at least in the context of the persecution of the church at the time).

Not everyone wants to, and not everyone who wants to can have children or find a spouse, and this has no bearing on their salvation.

Adoption is glorified by God (and not to say homosexual behavior is spiritually acceptable, but adoption and loving family are possible in homosexual relationships)

This makes it seem less a critical part of our relationship with God, and more a blessing like other blessings.
