"One little word will fell him!"
Now is the judgment of this world, now shall the ruler of this world be cast out.
1 John 3:8
The reason the Son of God appeared was to destroy the works of the devil.
Since therefore the children share in flesh and blood, he himself likewise partook of the same nature, that through death he might destroy him who has the power of death, that is, the devil.
[God] disarmed the principalities and powers and made a public example of them, triumphing over them in him.
John 16:8, 11
When the Counselor comes he will convince the world . . . of judgment, because the ruler of this world is judged.
I have appeared to you for this purpose, to appoint you to serve and bear witness . . . to open their eyes, that they may turn from darkness to light and from the power of Satan to God, that they may receive forgiveness of sins and a place among those who are sanctified by faith in me.
Submit yourselves to God. Resist the devil and he will flee from you. Draw near to God and he will draw near to you.
1 Peter 5:8
Resist him (Satan), firm in your faith.
Ephesians 6:11, 16
Put on the whole armor of God, that you may be able to stand against the wiles of the devil . . . above all, taking the shield of faith, with which you can quench all the flaming darts of the evil one.
He has delivered us from the dominion of darkness and transferred us to the kingdom of his beloved Son.
1 John 2:13
I write to you, young men, because you are strong, and the word of God abides in you, and you have overcome the evil one.
The accuser of our brethren has been thrown down . . . And they have conquered him by the blood of the Lamb and by the word of their testimony, for they loved not their lives even unto death.
And the devil . . .who had deceived them, was thrown into the lake of fire and brimstone where the beast and the false prophet were, and they will be tormented day and night for ever and ever.
I am sure that . . . neither angels nor principalities . . . nor powers . . . will be able to separate us from the love of God in Christ Jesus our Lord.
