So we just sit around and God will bring us a husband or wife? I don't think so. In every example in the Bible, God commanded His people to do something in order to achieve the goal. Some people like to use the example of Abraham and Sarah, where God promised children yet he got impatient and decided to get with Hagar instead, but that is totally irrelevant to us today. Did God promise you a husband or wife? No. So we can't just assume it's going to happen one way or another. We have to work for it. Then should we just compromise and marry an unequally yoked person? No, the Bible tells us not to for many reasons. But the point is that I do not believe that God will just automatically find a spouse for everyone. Can He help if we ask for the right reasons? I think so. But I still believe we have to put in our effort as well.
As far as internet dating goes, I have mixed feelings about it. I just find it to be a pretty awkward environment to meet people. It's more like a sales ad magazine. I think it's funny though how the girls with hot pics get like 800 messages a day from guys and the ones with not so hot pics get few to none. If you wanna find out how hot you are to the opposite sex, just post a pic of yourself on a dating site and see how many responses you get, LOL. That'll be a good little self-esteem experiment for ya.
And also, I think it's much harder to get a proper perspective on someone without seeing them in person. I suppose you could just set up dates and go from person to person but I personally don't like that style. I'd feel bad for getting someone's hopes up. Anyway... I think it may be worth a shot if you feel like you don't have any other options of finding a Christian but just be really careful and smart about it and take it VERY slow. I think you should be talking to them online often before you even meet.
