Spiritual warfare

God has given us 3 weapons to engage spiritual warfare with the devil.
1) The name of Jesus
2) The blood of Jesus
3) The word of God

"For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ." 2 Cor 10:4-5
