It’s not just upto you to value marriage. Your generation has had its time. You are lucky if you found someone sharing your values.
The 80+ percent of 18-year olds who have indulged in premarital sex (sex after three dates is more-or-less a norm) failed to value it. The remainder have a chance. And for how long? A decent career takes at least until age 25 to stabilise. What are your chances of finding someone who upholds the value of marriage, by then? Exceptions exist, but the norm trends towards the meaninglessness and futility in betting on a stable marriage for such a generation.
Those born past 1990 are going to face the brunt of this changed social dynamics. I doubt they have the fortitude to fare well in the upcoming chaos.
I’m not expecting to be a one man society changer; and God has made clear that He is the important One anyhow. Now it may be that once more deeply invested in God, then God’s people will succeed in sharing a transformation out of evil with society. America was fortunate to have gospel roots. Australia did too, at one time. But the world’s inexorable response to the gospel is eventually, “we don’t want it. We are doing just fine on our own philosophies and you old fuddy duddies can go away.”
