What I hear when you say you know Jesus:
"Thou believest that there is one God; thou doest well: the devils also believe, and tremble." James 2:19
This is what man does and says:
"13 Then certain of the vagabond Jews, exorcists, took upon them to call over them which had evil spirits the name of the Lord Jesus, saying, We adjure you by Jesus whom Paul preacheth.
14 And there were seven sons of one Sceva, a Jew, and chief of the priests, which did so.
15 And the evil spirit answered and said, Jesus I know, and Paul I know; but who are ye?
16 And the man in whom the evil spirit was leaped on them, and overcame them, and prevailed against them, so that they fled out of that house naked and wounded." Acts 19:13-16
This is what Jesus does and says:
"33 And in the synagogue there was a man, which had a spirit of an unclean devil, and cried out with a loud voice,
34 Saying, Let us alone; what have we to do with thee, thou Jesus of Nazareth? art thou come to destroy us? I know thee who thou art; the Holy One of God.
35 And Jesus rebuked him, saying, Hold thy peace, and come out of him. And when the devil had thrown him in the midst, he came out of him, and hurt him not.
36 And they were all amazed, and spake among themselves, saying, What a word is this! for with authority and power he commandeth the unclean spirits, and they come out." Luke 4:33-36
"For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart." Hebrews 4:12
"17 And the seventy returned again with joy, saying, Lord, even the devils are subject unto us through thy name." Luke 10:17
"23 And there was in their synagogue a man with an unclean spirit; and he cried out,
24 Saying, Let us alone; what have we to do with thee, thou Jesus of Nazareth? art thou come to destroy us? I know thee who thou art, the Holy One of God." Mark 1:23-24
"And unclean spirits, when they saw him, fell down before him, and cried, saying, Thou art the Son of God." Mark 3:11
"18 The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised," Luke 4:18
This is what Jesus says for you to do:
"Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord;" Acts 3:19
"For thou shalt worship no other god: for the LORD, whose name is Jealous, is a jealous God:" Exodus 34:14
This is what Jesus says for us as servants:
"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." Luke 10:19
"12 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." Ephesians 6:12
"17 And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;" Mark 16:17
"11 Put on the whole armour of God, that ye may be able to stand against the wiles of the devil." Ephesians 6:11
"18 The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised," Luke 4:18
What will happen if you do not turn from evil:
"But the children of the kingdom shall be cast out into outer darkness: there shall be weeping and gnashing of teeth." Matthew 8:12
What will happen if you do turn from evil:
"47 Wherefore I say unto thee, Her sins, which are many, are forgiven; for she loved much: but to whom little is forgiven, the same loveth little.
48 And he said unto her, Thy sins are forgiven." Luke 7:47-48
