Mortal sins kill and those who commit them will not inherit the Kingdom of God. That is why it is so very important to have witnesses and not bear false witness against another. It is a very grave sin, as is fornication (porneia). Anyone committing fornication or bearing false witness are in danger of Gehenna (”hell”).

So, will you stop with the ‘you think you’re saved because you believe you’re saved’ nonsense, considering that since you’ve been corrected REPEATEDLY, it would be false witness to claim so?
I still am quite confused as to what you’re trying to argue other than that sins are sins and we need the grace of God.
Let me reply to you with something else, however.
“27 “You have heard that it was said, ‘You shall not commit adultery.’ 28 But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart.”
How many mortal sins do you commit daily?
