 If you repeated that prayer after me, and you've never done that before, it happened to you as well. This is the day you got saved. This is the day you were born again. And you didn't have to repent, and you didn't have to be baptized. Now, after you've accepted Christ as your Savior, you may want to be baptized. That's fine. I encourage you to talk to a local pastor and tell him what you've done and follow his instructions. That's not how you get saved.
