You make a decent case.
But not one that has anything remotedly close to do with Christianity.
Why doesn't God want us to have sex before marriage?
Look at the history of marriage.
Then explain to me why pre-marital sex would be a problem for God.
I've looked at the history of marriage. That and your statement seem to emphasize an obsession with no-strings-attached sex, in which man can gratify his own lust, with no responsibility or accountability to woman, should she end up pregnant or with a disease.
Women, who have kids outside of wedlock, are far more likely to live in poverty. Kids are more likely to be dysfunctional, without a father in the home. Some of these kids end up being your friendly-neighborhood thieves and gangbangers.
Fatherless children, poverty for those children (and their mothers), STDs, the generating of social misfits, and emotional distress......all caused by sex outside of marriage. It's safe to say that the Lord has a problem with that.
Have you ever thought about the possibility that it may be that it is just the leaders of your church that has a problem with pre-marital sex, and that they use your God and religion to tell you what to do?
Instead of really having a sound base in the Bible and the actual actions of Jesus.
Jesus reiterated that "
For this reason shall a man leave his father and mother and cleave to his wife. And the two shall become one flesh" Nothing in His action has him condoning pre-marital/extra-marital sex in the least. Why else would he tell the woman caught in adultery, "
Go and sin no more.? Jesus made it clear that her behavior was wrong, a point not lost on her, since it nearly got her killed.
