The craftiness of Satan is clearly written in the Bible and it is important we understand and recognize his tricks and strategy.
So that we might not be taken advantage of by Satan, for we are not unaware of his
purposes. 2 Corinthians 2:11
Satan comes in a subtle manner and lures us into doing something that will make us fail in our walk with God. He tells us a little pornography does not hurt or bearing a grudge which becomes the root of bitterness is justified especially when we are mistreated. Satan also uses discouragement to attack us especially when anger, profanity, compromise and fear fails. He comes against us using our individual weak points and this makes the battle different for each person. Your weak point may be pride, envy, anger, doubt, impatience, pursuing forbidden pleasures or money, fame and power.
Don’t be ignorant of the enemy’s (Satan) devices because our spiritual life depends on it. He deceives people and is always persistent until the individual gives in.
