Not if they are saved christians, they wont believe such a thing.
Look at what Christ says exactly here in v37. However there are no righteous people except if they are in Christ having then His righteousness, so already we know these righteous are His children, not of the world.
37 “Then the righteous will answer him, ‘Lord, when did we see you hungry and feed you, or thirsty and give you something to drink? 38 When did we see you a stranger and invite you in, or needing clothes and clothe you? 39 When did we see you sick or in prison and go to visit you?’
40 “The King will reply, ‘Truly I tell you, whatever you did for one of the least of these brothers and sisters of mine, you did for me.’
So we see Christ is talking family members now. And He also early mentions dividing sheep from goat. Christ is the door of the sheep, not the goats. Christ dies only for the sheep, meaning Christ is the way to God for the sheep. Can not get to God except by that doorway. There are no family of God except they be in Christ, all others are of Satan.
John 10:7
[
Jesus the Good Shepherd ] Then Jesus said to them again, “Most assuredly, I say to you, I am the
door of the sheep.
John 10:8
All who
ever came before Me are thieves and robbers, but the
sheep did not hear them.
John 10:11
“I am the good shepherd. The good shepherd gives His life for the
sheep.
