Dating nor Courting is in the Bible but the principles of courting are. If you are skeptical, I understand. I highly recommend asking God if you should be dating and see what He says :) I think your eyes will be opened.
If you hear or see something long enough, you will believe it to be the truth. But just because the majority s doing _____ doesn't mean it is right nor that you should be doing it. We are told to "come out from among them and be ye different." 2 Corinthians 6:17.
