Mortal sin; is it real? So first, Hi everybody! I’m new to the forums after just having a real in depth conversation with my friends at a beach... Anyway, just am looking for a way to clarify things I have questions about and to learn even more about God’s Grace among other things. I am a recently converted Christian (from agnostic, previous to that Christian), non denominational, for background purposes. So here’s the point of the whole thread. Is there such a thing called a mortal sin; is there a sin that sends you straight to hell? My friends were talking how no matter what you do, your sins will always be forgiven as long as you believe and love Jesus and God and believe that His Grace can help save you from this sin. Is this true in your opinion? Do you have any ideas concerning this?
