No one writes "mortal sin". For it is not in the greek. We can sin unto physical death. But not spiritual death. I can do the same with thenx tverse to prove to you your quote is a reinterpretation of Scripture that is wqrong.
To say one can lose their salvation is to say that jesus did not forgive all your sins which is a lie. It says that slavbation requires work which is a lie. It say that an all knowing god who knows past present and future knew a person would get salvation and then God would have to revoke that salvation which is a lie. It also denies what Jesus said in Matt. 7:
22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
but according ot you , Jesu swould say to some- "I knew you once, but I don't know you now".
