I find it very interesting that most Christendom will agree with this statement but not in practice.
Jesus defeated/conquered satan, death and sin.
Most will affirm death and satan but not sin because they still sin.
But there are so many passages that speak of the old man was put to death, sin was put to death, be dead to sin and alive in Christ. Put on the new man, clothe yourself with Christ. There is human volition/will to obey loving what God loves and hating what God hates. There is an active crucifixion that needs to take place. A daily taking up your cross, deny self and follow/obey Christ. Putting on the full armor of God and put to death the flesh.
Galatians 5:24
Those who belong to Christ Jesus
have crucified [past tense and dead] the flesh with its passions and desires.”
Colossians 2:11
“In him you were also circumcised with a circumcision not performed by human hands. Your whole self ruled by the flesh
was put off [paste tense; what is circumcised/removed is never again part of the body] when you were circumcised by Christ,”

We were therefore buried with Him through baptism into death, in order that, just as Christ was raised from the dead through the glory of the Father, we too may walk in newness of life.
Romans 7:5
“For
when we were [past tense] in the realm of the flesh, the sinful passions aroused by the law were at work in us, so that we bore fruit for death.”

“You, however,
are not in the realm of the flesh but are in the realm of the Spirit, if indeed the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, they do not belong to Christ.”
2 Corinthians 5:16
Wherefore henceforth know we no man after the flesh: yea, though we have known Christ after the flesh, yet now henceforth know we
him no more.
Galatians 2:20
I have been crucified with Christ, and I no longer live, but Christ lives in me. The life I live in the body, I live by faith in the Son of God, who loved me and gave Himself up for me.
Colossians 3:5
Put to death, therefore, the components of your earthly nature: sexual immorality, impurity, lust, evil desires, and greed, which is idolatry.

Do not lie to one another,
since you have taken off the old self with its practices, / and have put on the new self, which is being renewed in knowledge in the image of its Creator.

The old has passed away. Behold, the new has come!

to
put off your former way of life, your old self, which is being corrupted by its deceitful desires; to be renewed in the spirit of your minds; / and
to put on the new self, created to be like God in true righteousness and holiness.

Instead,
clothe yourselves with the Lord Jesus Christ, and make no provision for the desires of the flesh.

have clothed yourselves with Christ.

Those who live according to the flesh set their minds on the things of the flesh; but those who live according to the Spirit set their minds on the things of the Spirit. / The mind of the flesh is death, but the mind of the Spirit is life and peace,
Romans 12:2
Do not be conformed to this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what is the good, pleasing, and perfect will of God.
1 Peter 4:1-2
Therefore, since Christ suffered in His body, arm yourselves with the same resolve, because anyone who has suffered in his body is done with sin. / Consequently, he does not live out his remaining time on earth for human passions, but for the will of God.
1 John 2:15-17
Do not love the world or anything in the world. If anyone loves the world, the love of the Father is not in him. / For all that is in the world—the desires of the flesh, the desires of the eyes, and the pride of life—is not from the Father but from the world. / The world is passing away, along with its desires; but whoever does the will of God remains forever.
