"And out of his mouth goeth a sharp sword,
that with it he should smite the nations. . . ,"
Revelation 19:15

This reminds us to pay attention to the Word
of God. When we know the Word of God, we
have the sword of the Spirit. And with the
sword of the Spirit, we can overcome every
thing in the world.

Jesus will bring a sword that comes out of His
mouth. With it He will smite the nations.
This is an analogy. He will impress them by His
words.
