Context: Jesus, in the Sermon on the Mount, teaches the way to God and explains His own mission on earth as the fulfillment of the old law rather than the destruction of it. He guides the people in almsgiving, prayer, judgment of one's fellows, and examination of one's self, and declares the Golden Rule to be the law. Asserting that destruction or damnation is found by those who take the easy way, He says that the eternal life or the Kingdom of Heaven is gained by the few who are willing to discipline themselves to a restricted (strait) and hard earthly existence:
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:
Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.
