What if 6 months into it, you fall in love with someone else?
People that choose to marry claim the same thing has happened to them.
Abraham sent his servant into another land to find his son a wife. Isaac never met her before and they didn't go through what people today call "dating". This doesn't mean that Isaac did not love her. Love is not a feeling, it is a choice and a commitment. One does not "fall out of love" with someone. They simply choose to no longer commit to loving that person. Of course this would imply that a person is responsible for their own commitment or lack thereof and most people don't want to hear that.
There are places on the earth where marriages are still arranged and those people commit to loving one another. The divorce rates have a tendency to be much lower or even nonexistent in those places.
Divorce, fornication, and adultery seem to flourish in places that support "do what FEELS right". This is the reason why I don't think dating is a godly method of finding a mate. Dating is a "relationship of convenience" that when it no longer FEELS convenient, you abandon the relationship. You get to enjoy the goods until you no longer feel like it. No where in scripture will you find anything that supports such a concept. It is simply ungodly and not the way God designed things to be.
Isaac's marriage was arranged by his father. Hosea's marriage was arranged by God.
Just something to consider.
