“Enter by the narrow gate. For the gate is wide and the way is easy that leads to destruction, and those who enter by it are many. For the gate is narrow and the way is hard that leads to life, and those who find it are few.

Matthew 7:13-14 (ESV)
“When the Son of Man comes in his glory, and all the angels with him, then he will sit on his glorious throne. Before him will be gathered all the nations, and he will separate people one from another as a shepherd separates the sheep from the goats. And he will place the sheep on his right, but the goats on the left. ”

Matthew 25:31-33 (ESV)

The lie is as wide as a freeway. The truth is as narrow as a footpath.
Or a single person.
