13 Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat:
14 Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.
As we read here in St Matthew Chapter 7:13-14 Christ teaches very clear that the road that leadeth unto life (eternal life) is a strait, narrow road. He also teaches that there will be few that find the road and the gate.
15 Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves.
Christ teaches very clearly that there will be false prophets that look great on the outside (sheep's clothing) but rather they are misleading and very dangerous (ravening wolves.)
20 Wherefore by their fruits ye shall know them.
21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
As we study these words we realize that we can know if there are true prophets on the earth. This passage of scripture teaches us how to tell peoples' intent by there actions. We need to look at the "fruits" then we need to pray about them and see if they are good or bad. The scriptures are true, "wherefore by their fruits ye shall know them."
