Jesus Christ fixed Satan

Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil; Heb 2:14 KJV
I [am] he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death. Rev 1:18 KJV
And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels, And prevailed not; neither was their place found any more in heaven. And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him. Rev 12:7-9 KJV
And the seventy returned again with joy, saying, Lord, even the devils are subject unto us through thy name. And he said unto them, I beheld Satan as lightning fall from heaven. 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. Luk 10:17-19 KJV
Most things happened on the cross and before the cross than most people know. Jesus Christ took the place of man in sin, sickness, poverty, death and every evil thing in the world. Jesus did not only carry our sins on himself, he also carried the whole world’s diseases and sicknesses, he carried all pains and afflictions and every evil thing in this world was laid on him.
He is despised and rejected of men; a man of sorrows, and acquainted with grief: and we hid as it were [our] faces from him; he was despised, and we esteemed him not. Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted. But he [was] wounded for our transgressions, [he was] bruised for our iniquities: the chastisement of our peace [was] upon him; and with his stripes we are healed. All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him the iniquity of us all. Isa 53:3-6 KJV
Jesus Christ went to hell in our place and there, he spoilt, defeated and stripped principalities, powers, dominions and the devil of all their power. Now we that are born again have been given the nature and life of the almighty God, and by having received God’s abundant grace and the gift of righteousness we are to reign and rule on this earth. God has given us the power that he used to raise Christ from the dead and made us to sit in heavenly places together with our Lord Jesus Christ. So rule child of God!
[For I always pray to] the God of our Lord Jesus Christ, the Father of glory, that He may grant you a spirit of wisdom and revelation [of insight into mysteries and secrets] in the [deep and intimate] knowledge of Him, By having the eyes of your heart flooded with light, so that you can know and understand the hope to which He has called you, and how rich is His glorious inheritance in the saints (His set-apart ones), And [so that you can know and understand] what is the immeasurable and unlimited and surpassing greatness of His power in and for us who believe, as demonstrated in the working of His mighty strength, Which He exerted in Christ when He raised Him from the dead and seated Him at His [own] right hand in the heavenly [places], Far above all rule and authority and power and dominion and every name that is named [above every title that can be conferred], not only in this age and in this world, but also in the age and the world which are to come. And He has put all things under His feet and has appointed Him the universal and supreme Head of the church [a headship exercised throughout the church], Which is His body, the fullness of Him Who fills all in all [for in that body lives the full measure of Him Who makes everything complete, and Who fills everything everywhere with Himself]. Eph 1:17-23 AMP
And the God of peace shall bruise Satan under your feet shortly. The grace of our Lord Jesus Christ [be] with you. Amen. Rom 16:20 KJV
