AMEN to this very important question!!
Prayer and fasting is definitely needed to stay away from the temptations of the devil.
Reading daily is clear way to know when the devil is using a false prophet or a confused believer to confuse us.
Also, when we rebuke the devil in someone, may we send it to a place to not come back to us; as we must realize that when we are used to rebuke a demon, that demon comes for us. Don't get paranoid, just send it to a place and pray and cover yourself with the blood of JESUS ( in prayer).
Passages to connect all this:
The ways of demons:
MATTHEW 12:43-45
“When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest, and findeth none. Then he saith, ‘I will return into my house from whence I came out.’ And when he is come, he findeth it empty, swept, and garnished.
Then goeth he, and taketh with himself seven other spirits more wicked than himself, and they enter in and dwell there; and the last state of that man is worse than the first. Even so shall it be also unto this wicked generation.”
Power of prayer and fasting to cast out demons and resist:
MARK 9:17-29
And one of the multitude answered and said, Master, I have brought unto thee my son, which hath a dumb spirit;
And wheresoever he taketh him, he teareth him: and he foameth, and gnasheth with his teeth, and pineth away: and I spake to thy disciples that they should cast him out; and they could not.
He answereth him, and saith, O faithless generation, how long shall I be with you? how long shall I suffer you? bring him unto me.
And they brought him unto him: and when he saw him, straightway the spirit tare him; and he fell on the ground, and wallowed foaming.
And he asked his father, How long is it ago since this came unto him? And he said, Of a child.
And ofttimes it hath cast him into the fire, and into the waters, to destroy him: but if thou canst do any thing, have compassion on us, and help us.
Jesus said unto him, If thou canst believe, all things are possible to him that believeth.
And straightway the father of the child cried out, and said with tears, Lord, I believe; help thou mine unbelief.
When Jesus saw that the people came running together, he rebuked the foul spirit, saying unto him, Thou dumb and deaf spirit, I charge thee, come out of him, and enter no more into him.
And the spirit cried, and rent him sore, and came out of him: and he was as one dead; insomuch that many said, He is dead.
But Jesus took him by the hand, and lifted him up; and he arose.
And when he was come into the house, his disciples asked him privately, Why could not we cast him out?
And he said unto them, This kind can come forth by nothing, but by prayer and fasting.
Rebuke the demon and put it some where ( cast it to a far away place):
MATTHEW 8:28-32
And when he was come to the other side into the country of the Gergesenes, there met him two possessed with devils, coming out of the tombs, exceeding fierce, so that no man might pass by that way. And, behold, they cried out, saying, What have we to do with thee, Jesus, thou Son of God? art thou come hither to torment us before the time?
And there was a good way off from them an herd of many swine feeding.
So the devils besought him, saying, If thou cast us out, suffer us to go away into the herd of swine.
And he said unto them,
Go. And when they were come out, they went into the herd of swine: and, behold, the whole herd of swine ran violently down a steep place into the sea, and perished in the waters.
GOD BLESS US ALL!!
