1 John
4:4 Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world.
4:5 They are of the world: therefore speak they of the world, and the world heareth them.
4:6 We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error.
You have already begun to win the victory because you recognize the enemy for who and what he is. The accuser of the brethren is real, but even He must gain permission from God...
Job
1:6 Now there was a day when the sons of God came to present themselves before the LORD, and Satan came also among them.
1:7 And the LORD said unto Satan, Whence comest thou? Then Satan answered the LORD, and said, From going to and fro in the earth, and from walking up and down in it.
1:8 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?
1:9 Then Satan answered the LORD, and said, Doth Job fear God for nought?
1:10 Hast not thou made an hedge about him, and about his house, and about all that he hath on every side? thou hast blessed the work of his hands, and his substance is increased in the land.
1:11 But put forth thine hand now, and touch all that he hath, and he will curse thee to thy face.
1:12 And the LORD said unto Satan, Behold, all that he hath [is] in thy power; only upon himself put not forth thine hand. So Satan went forth from the presence of the LORD.
You are positioned in the perfect place for spiritual warfare...
Matthew
17:18 And Jesus rebuked the devil; and he departed out of him: and the child was cured from that very hour.
17:19 Then came the disciples to Jesus apart, and said, Why could not we cast him out?
17:20 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.
17:21 Howbeit this kind goeth not out but by prayer and fasting.
