That is a problem, but look at the marriage rates in the Roman Catholic church for example.
You can claim many things, but they have been pretty serious about marriage. Yet Catholics are not getting married.
In my own synod (the LCMS), we are also very strict about marriage.
The issue is that people are not caring. Many would rather leave the church.
We have a Pope who says we have to spend less time on abortion and homosexuality, yet, I am a weekly attendant, minimum, at Mass and can not remember the words, contraception, abortion, homosexuality, ever being said in any of the Catholic Churches I have attended,. What I hear ad nausea is the LOVE of God. ‘God is all love’ . God Loves Us.
Sure God loves us, yet he is a vindictive guy. HE made Hell. HE condemns most to Hell if we are to believe scripture. Yet, almost all Christian denominations down play the Justice and punishment of God.
Why repent when not doing so has no ramifications.
