See Ephesians 6:12-18. The Bible tells us put on the full armor of God to thwart the fiery darts of the enemy. The Bible tells us that we do not war with flesh and blood, but with powers and principalities in high places (demons). The devil tried to tempt Jesus in the wilderness. Ephesians 4:27 - Neither give place to the devil. Keep in prayer and stand on the truth of God's words. We ask God for His help. God fights our battles for us, but we must stand on the Truth, and we must first know the Truth, in order to stand on it.
