When I turned from atheism to thinking that maybe God does exist it was because of a supernatural experience I had.
When I started to seek the God of the Bible it was because of another supernatural experience I had.
I became a Christian from reading the gospels.
These experiences brought about a change in my mind, in the way I thought and looked at the world and existence. After becoming a Christian and having a wonderful experience from God when I was baptized in Jesus name and then I spoke in tongues when I received the baptism of the Spirit, I still had to fight thoughts of doubt. I could have a might experience of God's presence and glory one day and the next day thoughts would come to my mind denying the existence of God! Those thoughts originated and came from the enemy of my soul, not from my own mind. I would have to resist those thoughts by remembering the experiences I had from God, often. It was a battle raging in my mind. That's where the battlefield is.
And example of how Satan influences people is Ananias and Sapphira.
Acts 5:3 But Peter said, Ananias, why hath Satan filled thine heart to lie to the Holy Ghost, and to keep back part of the price of the land? or Job's wife spoke the same similar words that Satan did to God. Coincidence? I don't think so.
1 Again there was a day when the sons of God came to present themselves before the LORD, and Satan came also among them to present himself before the LORD. 2 And the LORD said unto Satan, From whence comest thou? And Satan answered the LORD, and said, From going to and fro in the earth, and from walking up and down in it. 3 And the LORD said unto Satan, Hast thou considered my servant Job, that there is none like him in the earth, a perfect and an upright man, one that feareth God, and escheweth evil? and
still he holdeth fast his integrity, although thou movedst me against him, to destroy him without cause. 4 And Satan answered the LORD, and said, Skin for skin, yea, all that a man hath will he give for his life. 5 But put forth thine hand now, and touch his bone and his flesh, and
he will curse thee to thy face. 6 And the LORD said unto Satan, Behold, he is in thine hand; but save his life. 7 So went Satan forth from the presence of the LORD, and smote Job with sore boils from the sole of his foot unto his crown. 8 And he took him a potsherd to scrape himself withal; and he sat down among the ashes. 9
Then said his wife unto him, Dost thou still retain thine integrity? curse God, and die. 10 But he said unto her, Thou speakest as one of the foolish women speaketh. What? shall we receive good at the hand of God, and shall we not receive evil? In all this did not Job sin with his lips.
