We are taught that an angel who is in Divine truths from the Lord can terrify a whole host of evil spirits, and cast them into hell, merely by looking at them. They dare not come near him. Even though the angel might not be particularly strong in his body, he nevertheless has, by means of Divine truths from the Lord, the strength of a lion over evil spirits. Such is the power of Divine truth. Such is the power of faith in this truth.
Faith is, of course, far more than a matter of mere thought, mere belief.
To have faith in the Lord's truth means not only to believe, but also to love and live it. But, if we do this, if we truly trust in the Lord, and so do what He teaches us, we also, as to our spirits, will have the strength of a lion. No evil spirit will be able to destroy within us what is good from the Lord. The story of Daniel therefore contains an eternal truth. If we, as did Daniel, have faith in the Lord, then we will be safe from the onslaughts of the evil spirits of hell.
