The gospel path is strait and narrow in the sense that he who traverses the path must do so with care and must walk everlastingly with his eyes fixed upon the Lord and his anointed servants. The way is narrow. “Enter ye in at the strait gate,” the Lord said in the meridian of time,
“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”
(Matthew 7:13-14).
A modern revelation also explained:
“Strait is the gate, and narrow the way that leadeth unto the exaltation and continuation of the lives, and few there be that find it, because ye receive me not in the world neither do ye know me.... Broad is the gate, and wide the way that leadeth to the deaths; and many there are that go in thereat, because they receive me not, neither do they abide in my law.”
(D&C 132:22, 25; see also 2 Nephi 31:19-20.)
