Colossians 2

¹³ And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses;

¹⁴ Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;

¹⁵ And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.

Hebrews 9

¹⁴ How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?

²² And almost all things are by the law purged with blood; and without shedding of blood is no remission.

Hebrews 10

¹¹ And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins:

¹² But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God;

¹³ From henceforth expecting till his enemies be made his footstool.

¹⁴ For by one offering he hath perfected for ever them that are sanctified.

¹⁵ Whereof the Holy Ghost also is a witness to us: for after that he had said before,

¹⁶ This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them;

¹⁷ And their sins and iniquities will I remember no more.

¹⁸ Now where remission of these is, there is no more offering for sin.

¹⁹ Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus,

²⁰ By a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh;

²¹ And having an high priest over the house of God;

Satan and his evil forces are mentioned as in Ephesians 6

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.

At the time of Christ’s crucifixion,

Colossians 2

¹⁵ And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.

1 John 3:8

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.

satan was defeated at the time of Christ’s crucifixion and when Christ had disarmed the rulers and authorities, He made a public display of them, having triumphed over them.

What is the future of satan and his evil forces?
