Matt.7: 21-23, why are those that believe in Christ being condemned? They are pleading to Christ (A sign of belief) and Christ is ignoring their excuses, hence not being forgiven. Again, what was the reason (In Matt 7: 13-26).
If many are called, why are so few chosen? ... Because so few will let HIM do it, transform them by raising them up in the way that they should go. Those who profess to believe in Jesus as Lord of THEIR life but who actually reject HIS raising are the ones JESUS never knew. They will be rejected at the Great White Throne.
Because there's a difference between head knowledge and a real relationship of faith and trust.
You can know about someone and not know them.
They are pleading because they don't want to go to hell, a normal response, I'd say.
But notice, they are appealing to their works.
People many times profess Christ for what they can gain from using His name and I'm pretty sure that God is not going to be used by anyone.
