The strait (narrow) path to immortality

Matthew 7:13-14 KJV

(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.

Luke 13:24 KJV

Strive to enter in at the strait gate: for many, I say unto you, will seek to enter in, and shall not be able.
