There is an evil day of temptation, an evil day of doubt, and an evil day of fear. But there is an answer to this fear; and under the inspiration of God it comes from David himself:
"What time I am afraid, I will trust in thee."—Psalm 56:3.

We ignore the Lord's instructions to our own destruction. If we neglect to do what God has told us to do, we will pay a heavy price.
We must "put on the whole armour of God so that we may be able to withstand in the evil day, and having done all, to stand."
