Enter through the narrow gate. Wide is the gate and open is the way leading to destruction, and there are many who enter through it. Narrow is the gate and difficult is the way leading to life, and there are few who find it. Be careful of false prophets, who come to you in the guise of sheep but underneath are ravenous wolves. By what they produce you will know what they are.
Every good tree produces fine fruit, but a bad tree produces lousy fruit.
A good tree cannot produce lousy fruit, nor can a bad tree produce fine fruit. Every tree that does not produce fine fruit is chopped down and tossed into a fire. By what they produce, then, you will know what they are. Not everyone who says to me, Master, master, will enter heaven's kingdom, but only one who does the will of my father in the heavens. Then I shall announce to them, I never knew you.
