Don't let sin become "acceptable"

There are different sins that we notice the unsaved{or even backslidden Christians} do, and we speak on them. But here's one I see becoming more common, in fact quite common,and it is, yes, a sin!These unmarried "couples", maybe "going steady " even engaged,who "get a jump on things" and have a baby outside of marriage.{or at least the woman gets pregnant before marriage.} I see this more and more often, and not only that, but the other unsaved people cheering them on.{or Christians who are afraid to sound judgemental}.In other words, the pattern I see, the woman gets pregnant first, then some time later, announces they'll "decide to" get married.But is this sin?Let's face it, the old story about you can get pregnant from swallowing a watermelon seed isn't true.They had to have sex for her to get pregnant.And if that sex was at a time before they were married, {and sometimes they don't even get married}wouldn't that be considered fornication?. To me, it seems pretty clearly, yes.But like I say,this is happening more and more often,and others "cheer them on."Fornication, which is sin? I'd say so. You?
