A word shall quickly slay him

And were this world Devils o'er,
And watching to devour us,
We lay it not to heart so sore;
Not they can overpower us.
And let the Prince of ill
Look grim as e'er he will,
He harms us not a whit,
For why? His doom is writ;
A word shall quickly slay him.

Amen.
This is a verse from the hymn we sang in church on Sunday. While we were singing it,  the Holy Spirit started ministering to me.
No matter what I think I've seen or what I'm seeing or whatever I will see, I don't need to think too much about it. Even if the whole world is filled with evil we shouldn't take it to heart. In other words it doesn't concern us.
Let the devil look as wicked as he wants, He can't harm us.

This is the best part.
One word from my mouth will quickly disarm him.

One word from your mouth will quickly slay him. Isn't that wonderful.

Christ has given us power.  Mark 16:17
