I mentioned Zechariah 3 in post #21. Also important is Colossians 2:14-15.
'.....Having wiped out the certificate of debt [NKJV margin] with its requirements that was against us, which was contrary to us,. And He has taken it out of the way, having nailed it to the cross. Having disarmed principalities and powers, He made a public spectacle of them, triumphing over them in it.'
These verses connect Christ's triumph to the cross, and precisely to the bond of our debt, as defined by the ordinances of the law. when He was crucified. It is then and there that the principalities and powers, the chief of whom is Satan, were 'disarmed.'
This concerns judicial claims. Since God is expected to uphold the rules that He has set, we can also expect that the cancellation of the claims was obtained by the payment of the legal debt. This is confirmed by the many 'ransom' sayings that declare that the life or blood of Christ was the price paid to free human beings from bondage.
What is the image presented of a certificate of debt being nailed to the cross? It is that of a bill being nailed there, marked tetelestai-- 'paid in full.'
Revelation 12 reflects the same understanding. How have the brethren overcome the devil and hid forces? Not by superior power, but 'by the blood of the Lamb' (v.11). Satan was the accuser of the brethren (v.10), and he could prevail as long as he could point to their (the brethren's) sins. But the blood of the Lamb was the price paid for the cancellation of their debt. Christ's suffering and death wiped out the guilt of their sins forever, and the devil has been disarmed.
Similarly, Hebrews 2:14 stresses that the Lord Jesus has deprived Satan of his power through His death and we are told that 'He is the Mediator of the new covenant , by means of [His] death, for the redemption of the transgressions under the first [Mosaic] covenant , that those who are called may receive the promised inheritance' (Hebrews 9:15), His blood obtaining the remission of their sins (Hebrews 9:22, 27-28).
So Christ is indeed victorious; He has disarmed Satan and his forces, but He has done so by satisfying the demands of God's justice, thereby depriving Satan of his power to accuse the brethren.
Irenaeus seems to have understood this when he wrote, 'He who was powerful Word and also truly man redeemed us by His own blood.......and gave Himself as a ransom for those who had been taken into captivity.........The Lord redeemed us by His blood and gave His life for our life, His flesh for our flesh.....' It is a pity that Irenaeus' followers of recent times, like Gustav Aulen, did not have his perception.
