See post 42.
um.. post 42 doesn’t mention anything about your denomination.
If you are a protestant in a denomination without baptism.. and you are in church and the pastor calls you to the front to receive Christ. He says something along the lines of “do you accept Jesus into your heart and proclaim him to be your lord and savior?” In a denomination with Baptism you would added water in some form, either dribbling of full emersion.
But that’s it. You are saved at that point. Knowing the answers to no other mysteries is required.
