Satan's Devices or Mind Tricks
Satan lures men to fight a battle with him in their own strength on his ground and his way. He also tries to mold our thinking from a very young age. When men agree with the enemy, they either act like the enemy or they engage in his activities, and this becomes one of Satan's primary ways of battling the believer; through evil thoughts and through evil men who are controlled by his thoughts.
Lest Satan should get an advantage of us: for we are not ignorant of his devices.
- 2 Corinthians 2:11 ( (KJV)
