For me, I think that God has not called me to look for a wife. In general, I think that there are very few people who sign up for dating sites because they are led by God there. I'm sure that God might lead some people to them, but I can't think of anyone off the top of my head.
On the other hand I am sure there are times He actually shows you where you are going and where He is leading
I am not saying God DOES lead people to dating sites...but in our walking and living for and trusting God, even if we venture into that world.. He goes with us as long as it's not sinful and you know the difference..
