228. How keen the perception of angels is in detecting whether anything entering in is contrary to the truth of faith and to good springing from love defies description. The nature of that which enters in and the point at which it does so they perceive a thousand times better than man does himself, who knows scarcely anything about it. Angels are able to perceive more in the smallest degree of a person's thought than he himself in the largest; this is indeed incredible but absolutely true.
Genesis 3:11-13
11
And he said, Who told thee that thou wast naked? Hast thou eaten of the tree, whereof I commanded thee that thou shouldest not eat?
12
And the man said, The woman whom thou gavest to be with me, she gave me of the tree, and I did eat.
13
And the LORD God said unto the woman, What is this that thou hast done? And the woman said, The serpent beguiled me, and I did eat.
