The Bible never minimises the power of our great enemy, Satan. He is a real person with great power, long experience and apparent success; and he has at his disposal a great army of other fallen spirits – “the rulers of the darkness of this world” – which are well-organised and implicitly obedient.
(Fred Mitchell)
"I will say of the LORD, 'He is my refuge and my fortress, my God in whom I trust'."
Psalm 91: 2
