Yes. Divorce can be a traumatic experience for a person, I have known men who were divorced years, even decades earlier and are still hurting over it, emotionally and financially. With 'no fault divorces' a man can feel likes he is doing all the right things, do his best and then still be squelched on, having a life turned upside down. It is counter-intuitive and counter-Biblical. Younger men may see this and be wary. If divorce rates are varying between a quarter and a half of marriages, that's pretty grim odds of having your life wrecked.
Divorce statistics change but I have seen surveys which show that the divorce rate is higher among identifying Christians than among the general population, and surveys which show that Christians have a much higher divorce rate than Hindus, Muslims or Atheists. For example
https://christian-witness.org/christian-divorce-statistics/ , 66% of divorced adults in the USA identify as Christian while 62% of adults identify as Christian. Amongst Christians the rate of divorce is highest among Evangelicals. It's therefore a question to ask, Jesus told his church to be salt and light, why then is the divorce rate higher among church goers than non church goers?
I don't believe by and large the modern church has a biblical world view, humanism, prosperity gospel, feminism, socialism are all creeping in and infecting pulpits. The bible warns that a time will come when preachers will tell people whatever they want to hear (2 Timothy 4:3) for the sake of popularity. I have even encountered churches that are ok with couples cohabiting, scared of losing them. Different churches seem to teach different things on marriage and sexuality or indeed any issue, sometimes these different things are not biblical, they contradict each other and contradict the bible. Some denominations marry people of the same gender, increasingly now so.
IMHO a believer should be seeking marriage with someone who has a biblical worldview, but it can be hard to find a church or congregation with a biblical worldview now. For example:
https://www.christianitydaily.com/n...a-survey-reveals-family-research-council.html This research found that only 6% of Americans had a biblical worldview, while 48% claim to be living a Christian lifestyle. That's 42% of Americans who think they're living as Christians but don't know what it is to live as a Christian.
So to answer the question why are there so many single people:- it's difficult to find someone to be equally yoked with, there's a high risk of a marriage catastrophically imploding and there is confusion among Christians and Churches as to what marriage actually is.
God Bless.
