1Jn 3:1  Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not.
1Jn 3:2  Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
1Jn 3:3  And every man that hath this hope in him purifieth himself, even as he is pure.  The context here is a persons heart being purified from fear.  In the next chapter John talks about the fear that was in our hearts being replaced with the love of God.  Jesus is pure, meaning he has no death in him.  He was raised up in glorified immortal flesh that can never be touched by death again.  Everyone who has the surety that this same life will manifest in them is purified from fear by that certainty.  
1Jn 3:4  Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.
1Jn 3:5  And ye know that he was manifested to take away our sins; and in him is no sin.
1Jn 3:6  Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him.
1Jn 3:7  Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.  
1Jn 3:8  He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.

John says the Son of God was manifested to destroy the works of the devil. 

When John talks about the Son of God being manifested, he’s talking about the Father having brought Jesus forth from the grave in glorified immortal human flesh that can never die or taste weakness again. 

How does that destroy the works of the devil?  

Jesus says in John 8:44 the devil was a murderer from the beginning.  The Devil wants to uncover death in your sight so he can sting your heart with fear.  He wants to stain your conscience with a life that is perishable and full of death and corruption so he can fill your hearts with fear and cause you to take upon yourself the burden of manifesting life.

1st John says those who reject the word of life that manifested in the body of Jesus’ resurrection are walking in darkness.  Jesus says in Matthew 6 if your eye be sick then your whole body will be covered in darkness.  

The devil wants to make your eye sick so your body becomes decorated in the fruit of his death.  The way he tries to make your eye sick is by filling your sight with the death thats in the world.  A sick eye is an eye that is filled with death.  The Devil wants to use the death and the tribulation and the injustices in the world to sting your heart with fear and darken your understanding with the carnal mind. 

The apostle Paul says the carnal mind cannot comprehend God.  The carnal mind is at odds with Gods thoughts.  In the garden when Adam’s nakedness was uncovered, the carnal mind told Adam God abandoned him, when Gods thoughts were filled with seeking Adam to cloth upon his nakedness.

The carnal mind makes it to where a person cannot comprehend that God is with them to be a Shepherd to their lives.  It makes it to where a person cannot see that God has taken thought of them and taken thought to care for their life above all they can ask or think.  

The carnal mind is earthy.  It reasons from the life it sees in the world, and because of that it can only comprehend the death and tribulation it sees and the fear it feels.  The carnal mind is a mind so captivated with the fear of death that it leaves a person in the place where all they can think of is their own working to gather life to themselves.  It cannot comprehend the work of God so it leaves a person in the place where the burden of seeing life manifested in on them. 

If we look at Adam in the garden of Eden it paints a picture of the works of the devil.  The devil uncovered Adams nakedness in the garden.  It wasnt GOD who uncovered Adam’s nakedness.  Remember God asked Adam who told you that you were naked.  God can’t be the one who clothed and the one who uncovers.  

The uncovering of a persons nakedness is what happens when their eye is filled with the death they see all around them.  The tree of the knowledge of good and evil stained Adams conscience with death and stung his heart with fear.  Adam was filled with fear at the thought of death, and what could happen to his life.  He saw his nakedness, he saw he wasnt clothed in life, and that stung his heart with fear, and gave birth to the carnal mind in him.  He couldnt comprehend God.  He was enveloped by the darkness of the death he saw all around him.  He couldnt see God was with Him to be the Father he needed.  He couldnt comprehend the Father’s love for him; that the Father wouldn’t suffer him to see corruption; that God was with him to cloth upon his nakedness with the robe of His own life.  And so he tried to cloth himself with life.  That is the handy work of the Devil.  

1st John says God destroys the work of the Devil by purifying our hearts from fear.  And it says the way God purifies our hearts from fear is by manifesting the Son of God in our midst.  

God sees the fear that is tormenting us is because of the death in the world and the death that found an opportunity to manifest in our bodies.  He says if I can prepare myself a body that can take the death thats in the world into itself, where that death is able to fully manifest and do its worst, and then I can manifest my life in that same body, and consume the death that is there to the point where there is no remnant of death any longer, and that body is now glorified with my immortality, never to be able to be touched by death again, and I can do that in the midst of the world.  That will abolish death in the sight of my people.  That will destroy the body of sin that is serving my people with fear.  They will be able to see they arent lambs being led away to a slaughter; they will be able to see that I am their Shepherd and I am with them Shepherding them with my life, and their hearts will be flooded with my love.   

Jesus is quoted in the letter to the hebrews saying to the Father a body you have prepared for me that we might cleanse the conscience of our people from death and the fear of death that has taken them captive.  

The love of God is found in what He’s done in Christ to condemn death in the flesh.  1st John says God is love.  Within God is the kind of love that can perfect your heart from fear.  God is love is talking about what was manifested in Jesus.  God is love was manifested in the resurrection and ascension of Jesus.   It was manifested in the Father raising Jesus from the dead, having put off of him the body of death, and having clothed upon him with glorified immortal flesh.  1st Timothy speaking of the resurrection of Jesus says God was manifest in the flesh.  The kind of love that can send fear away from your heart and keep your heart from fear can only be found in the word that within God is a life that overcame death in the flesh, and He has freely given you this life in Jesus.

The Apostle Paul comes at it from a bit of a different angle in his letter to the romans, but in the latter part of Romans 7 Paul describes what the work of the devil looks like in a persons life.  Paul talks about the body of death and the condemnation it worked in him, and then he describes how God destroyed the work of the devil by destroying the body of death in the resurrection of Jesus. 

Paul says I thank God for the law of the Spirit of Life in Christ Jesus for it has set me free from the law of sin and death.  When I was being tormented by the death manifesting in my body and in the world around me God did what the law couldnt do and He came and destroyed the body of death.  He condemned the death that was working condemnation in me in the body of Jesus’ resurrection.  

Whereas before, my eye was sick, and I couldn’t comprehend that God was with me to cloth upon me with His life, and all I could see was the death and the fruit of death all around me.  Now my eye is single, and all I see is God manifested in the flesh.  Where my heart was once filled with fear, the love of God has been perfected in my heart.  The love of God has circumcised my heart from fear.  The death in the world can no longer separate me from the love of God.  

Paul is talking about the love of God in contrast to fear just as John did in 1st John.  Paul says the death in the world can no longer fill my heart with fear.  My heart has been purified with the love of God because I see God was manifested in the flesh.  That which is perfect is been born in my heart.  It never fails me when the tribulation encompasses me.  Whether peril or sword or famine or shipwreck or being stoned and left for dead, none of those things can replace the love of God in my heart with fear, because I have the certainty the death in the world and the death in my flesh is overcome in Christ.  Fear cannot replace the love of God in my heart because I see the work God has done to condemn death in the flesh. 

If we look at Adam God destroyed the works of the Devil by manifesting Himself to Adam.  Adam wasnt able to comprehend God with him because he was enveloped in the darkness of the death he saw, and God manifested Himself to Adam by clothing upon his nakedness.   And that destroyed the works of the Devil in Adam’s life.  

1st John 1 talks about people walking in darkness because their hearts and their minds arent filled with an incorruptible life, and the testimony that God has given them His incorruptible life as a gift in Jesus.  

God has an incorruptible seed in Himself that overcame the death in the world and even overcame the death in our physical bodies, and He has dispersed that seed to us freely in Jesus.  We have the seed of an incorruptible life dwelling in us now, even as we walk in a world that is still corruptible.  

If you find yourself feeling fear and anxiety over the tribulation in the world; if you find yourself fearful of the death in the earth and whether it will come upon you or your family.  The answer is for your heart and your mind to be set on the indestructible life God has in Himself, that was manifested in the body of Jesus’ resurrection.  God anointed Jesus Christ of Nazareth to baptize you with a life that is as a fire that consumes death to uttermost, never ceasing til there is no more death anywhere in your bodies or in the earth.

All your fears come from your mind being filled with the life that’s in the world, and that’s because the life that’s in the world is filled with death.  

As you pray with God about what He’s done to overcome death in the flesh.  As you meditate on how God has abolished death and brought to light immortality in the resurrection of Jesus, the love of God will find you.  Your heart will be circumcised from fear and it will be flooded with the fruit of the Spirit.  The peace of God; the peace that passes understanding is found in partaking with God in a life that overcomes death.  Its found in feeding on the word of a life that has beaten the grave and the tribulation in the world.
