Matthew 7:14-15

But small is the gate and narrow and difficult to travel is the path that leads the way to [everlasting]life, and there are few who find it. [Deut 30:19; Jer 21:8] “Beware of the false prophets, [teachers] who come to you dressed as sheep [appearing gentle and innocent], but inwardly are ravenous wolves. [Ezek 22:27]
