You want to know this for real!
By the name, blood, authority of Christ Jesus, we in Christ Jesus, He is in us through the Holy Spirit: We have legal authority and supernatural ability to defeat Satan, all his demons (fallen angels, or evil angels). They have absolutely no power over us! And to heal all manner of sicknesses, and illnesses.
Listen up:
“And he said unto them, I beheld Satan as lightning fall from heaven. Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you. Notwithstanding in this rejoice not, that the spirits are subject unto you; but rather rejoice, because your names are written in heaven.”
Luke 10:18-20 KJV
