SPIRITUAL WARFARE

Luke 10:19 KJV
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.

Ephesians 6:12 KJV
For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.

Matthew 17:19-21 KJV
Then came the disciples to Jesus apart, and said, Why could not we cast him out?

And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.

Howbeit this kind goeth not out but by prayer and fasting.
