That’s pretty funny. I’m afraid that what it indicates, rather, is a failure in reading comprehension in your not understanding the difference between say and do, and that your declaring it a poor argument is a desperate attempt on your part to divert attention from the facts. In other words, it’s a red herring and not an argument.
Your bottom line is imaginary. It is notable that you did not respond to my subsequent point, which is where the real bottom line is, and which line you have not yet reached:
Please note that Jesus’ statements were in reverse order to how I argued them. He prefaced his statement about ‘many will say’ with ‘only the one who does the will of my Father who is in heaven.’ What follows is Jesus giving a case in point, the point being that they have not done God’s will.
And then what does he say to them?
I will tell them plainly, ‘I never knew you. Away from me, you evildoers!’
And here all this time you have been arguing that they did indeed know him at some point, were ‘born again’ and yet somehow ‘lost it’, lost having been birthed and thus having gone back into an antepartum condition. Good trick. What has been lost is… well, never mind.
After over ten weeks of my arguments trying to penetrate the impenetrable, I think I have learned something. 
Shalom. ← (Take that in the parting, goodbye ‘God be with ye’ contraction, sense of the word.)
