as that we shall become acquainted with his devices."
Great Controversy p.516 E.G.W.
Woe to the inhabiters of the earth and of the sea!
for the devil is come down unto you, having great wrath,
because he knoweth that he hath but a short time.
Lest Satan should get an advantage of us:
for we are not ignorant of his devices.
2 Corinthians 2:11
