Not yet. Note I am not condoning premarital sex. And of course premarital sex can lead to “premarital” pregnancies. I am not condoning that either. I do think that babies are the gift of God’s creation and so the best possible reaction to premarital pregnancy is to get married. I don’t think it’s any better to have premarital sex and use birth control or have abortions. But in a perfect world (well, my perfect world) that wouldn’t be an issue. But we are in a fallen world, and being humans in this fallen world we do stupid and sinful things. So the next step is to make the best possible outcome. In this case I think they are doing that. I don’t know what Sarah Palin taught her daughter, I don’t know what her daughter was or wasn’t thinking. I don’t know if the pregnancy was the product of the one time they went too far, or the 50th time. But I think all of that is irrelevant, and most of it is none of our business.
I can tell you from my own experience you can teach your kids and try and lead by example and sometimes they just don’t do what you wish and they make mistakes you know they will pay for in many ways. I’ve got one like that and all I can do is pray for her, and on the other hand I have one who couldn’t have turned out any better and it amazes me what a terrific person he is. So all you can do is make the best of what the good Lord decided to put on your plate. That is often the real test of the person.
IMHO, I’d keep it simpler than that.
1) Instead of reacting, respond, as always through faith in Christ.
2) Respond by becoming responsible parents.
3) The opportunity for marriage exists, but the basics of identifying the right man and right woman precede marriage. Sexual intercourse isn’t the same as a marital love. Don’t become unequally yoked if one is a believer and one is not. Even if not married, that doesn’t relieve either father nor mother of their parental responsibilities. As the situation has been described, the couple is engaged to be married. Keep it simple with encouragement to make the right decisions, and always through faith in Christ.
4) Volition, marriage, family, and national governance are all divinely established institutions for believer and unbeliever alike. As long as the legitimate authority of those institutions are obeyed, they provide blessings for believer and unbeliever alike. For every cursing their is a blessing through faith in Christ. It’s far smarter to allow a cursing be turned into a blessing, than turning a blessing into a cursing.
5) IMHO, I wouldn’t demand the pregnancy to force a marriage, but I would rejoice if a marriage and family are the blessings of their life through faith in Christ.
