Fallen man is Satan's lawful captive. The mission of Jesus Christ was to rescue him from his power. Man is naturally inclined to follow Satan's suggestions, and he cannot of himself successfully resist so terrible a foe, unless Christ, the mighty conqueror, dwells in him, guiding his desires, and giving him strength. God alone can limit the power of Satan. He is going to and fro in the earth, and walking up and down in it. He is not off his watch for a single moment, through fear of losing an opportunity to destroy souls. It is important that God's people understand this, that they may escape his snares. MYP 51.1
