"If we follow Christ"
This idea that Man is fallen enough to deserve damnation but good enough to choose to save himself is totally unbiblical.

"We are all the elect."
No. Only the saints who God grants preserverance in Christ were truly regenerated to begin with.
People can decieve to themselves about their salvation in order to comfort themselves.
There are millions or unsaved Christians who say "Lord, Lord".
I was being vague in "follow Christ" but specifically that means recieving His sacraments. Only through His sacraments can we be saved as through Him we become more perfect as our Heavenly Father is perfect. Baptism is necessary, confession if fallen into mortal sin is necessary, communion is necessary. You are correct in saying that most "Christians" will say "Lord, lord" but be devoid of the sacraments and live in mortal sin and thus be deserving of The Judgement. This is the ancient understanding of "following Christ" corroborated by writings from apostles, early church fathers, all the way to Thomas Aquinas and later.
Faith alone saves, sir. The sacraments are ceremonies of obedience that matures one in sanctification.
Faith without works is dead. Demons believe in Jesus yet they will never be saved as they do naught but evil.
The thief on the cross would disagree with you.
