In the Words of the Enemy

This video pretty well sums up who you face every day. After the video I inserted a chapter from John Pipers Book. When I Don't Desire God

It is important to have a balance when exposing the character and works of Satan. And John Piper does a good job in the following writing.

GIVE THE DEVIL HIS DUE, BUT NO MORE

If you ask about the devil’s role in your darkness, I answer: Give him his
due, but no more. He and his demons are always at work, not just sometimes.
There is nothing extraordinary about the fact of his harassment.
Paul considers it a normal part of Christian warfare to “take up the
shield of faith, with which you can extinguish all the flaming darts of
the evil one” (Eph. 6:16).
16 In all circumstances take up the shield of faith, with which you can extinguish all the flaming darts of the evil one;

Peter counsels us, “Be sober-minded; be watchful.
Your adversary the devil prowls around like a roaring lion, seeking
someone to devour. Resist him, firm in your faith” (1 Pet. 5:8-9).
Be sober-minded; be watchful. Your adversary the devil prowls around like a roaring lion, seeking someone to devour. 9 Resist him, firm in your faith, knowing that the same kinds of suffering are being experienced by your brotherhood throughout the world.

All this is normal. But the quality of his harassment varies from mild temptation
to murder. Jesus calls him “a murderer from the beginning” (John 8:44).
You are of your father the devil, and your will is to do your father’s desires. He was a murderer from the beginning, and has nothing to do with the truth, because there is no truth in him. When he lies, he speaks out of his own character, for he is a liar and the father of lies.

He has the power to inspire painful persecution and even kill
Christians (Rev. 2:10).
Do not fear what you are about to suffer. Behold, the devil is about to throw some of you into prison, that you may be tested, and for ten days you will have tribulation. Be faithful unto death, and I will give you the crown of life.

But there are three great comforts in the face of Satan’s attacks.

One is that Satan cannot do anything apart from God’s sovereign permission
(Job 1:12; 2:6),
12 And the LORD said to Satan, "Behold, all that he has is in your hand. Only against him do not stretch out your hand." So Satan went out from the presence of the LORD.
6 And the LORD said to Satan, "Behold, he is in your hand; only spare his life."

which is governed by God’s infinite wisdom and covenant love. Thus Satan’s servants become God’s sanctifying envoys
(2 Cor. 12:7-10).
7 So to keep me from becoming conceited because of the surpassing greatness of the revelations, a thorn was given me in the flesh, a messenger of Satan to harass me, to keep me from becoming conceited. 8 Three times I pleaded with the Lord about this, that it should leave me. 9 But he said to me, "My grace is sufficient for you, for my power is made perfect in weakness." Therefore I will boast all the more gladly of my weaknesses, so that the power of Christ may rest upon me. 10 For the sake of Christ, then, I am content with weaknesses, insults, hardships, persecutions, and calamities. For when I am weak, then I am strong.


So even if Satan has a hand in your darkness, he is not
free to do more than your loving Father permits, and God will turn it
for your good (Luke 22:31-32).
32 but I have prayed for you that your faith may not fail. And when you have turned again, strengthen your brothers." 33 Peter said to him, "Lord, I am ready to go with you both to prison and to death."

Second, the decisive blow against Satan’s destructive power was
delivered by the death of Jesus for our sins (Col. 2:15
15 He disarmed the rulers and authorities and put them to open shame, by triumphing over them in him.
Heb. 2:14).
14 Since therefore the children share in flesh and blood, he himself likewise partook of the same things, that through death he might destroy the one who has the power of death, that is, the devil,

This means that Satan can harass us and even kill us, but he cannot destroy
us. Only unforgiven sin can damn the human soul. If Christ has covered
all our sin by his blood, and if God imputes to us the perfect righteousness
of Christ, then Satan has no grounds for any damning accusation,
and his case against us fails in the court of heaven. “Who shall bring any
charge against God’s elect? It is God who justifies. Who is to condemn?
Christ Jesus is the one who died” (Rom. 8:33-34).
33 Who shall bring any charge against God’s elect? It is God who justifies. 34 Who is to condemn? Christ Jesus is the one who died—more than that, who was raised— who is at the right hand of God,(D) who indeed is interceding for us.


THE DEVIL CANNOT ABIDE WITH THE LIGHT OF
CHERISHED TRUTH

Third, deliverance from Satan’s oppressing, darkening, and deceiving
work in the life of the Christian comes most often by the power of truth,
and only rarely by exorcism. I have seen demon-possession and have
been a part of one very dramatic exorcism. I don’t believe the person was
a Christian till after the deliverance. The complete takeover of the personality
by a demon is not something the Holy Spirit would allow in the
Christ-indwelt heart. But that distinction may not matter much to the
Christian who is being attacked and harassed from without on every
side. The battle can be fierce. What is called for usually is the ministry
of 2 Timothy 2:24-26.
24 And the Lord’s servant must not be quarrelsome but kind to everyone, able to teach, patiently enduring evil, 25 correcting his opponents with gentleness. God may perhaps grant them repentance leading to a knowledge of the truth, 26 and they may come to their senses and escape from the snare of the devil, after being captured by him to do his will.

The Lord’s servant must not be quarrelsome but kind to everyone,
able to teach, patiently enduring evil, correcting his opponents with
gentleness. God may perhaps grant them repentance leading to a
knowledge of the truth, and they may escape from the snare of the
devil, after being captured by him to do his will.
Gentle, loving, teaching of the truth is the process in which God himself
grants repentance and a knowledge of the truth, which results in an
escape from the captivity of the devil. The devil cannot abide truth and
light. He is by nature a liar and deceiver. He thrives in darkness.
Therefore, if, by God’s grace we can bring the full force of truth to shine
in the believer’s darkness, the devil will not survive the light. Good, solid
Bible teaching is a crucial part of deliverance from the darkening power
of the devil.
