The Circumcision of Christ is the replacement of the Sinful Nature with the Divine Nature. When Christ gives a person His Divine Nature, that is the moment that a human is no longer influenced by the mind of Satan. That influence is completely gone, for the Devil has been defeated. When the Devil is defeated, that is the moment that we have escaped corruption. Remaining sin is that of our mind; our habits . . . and these habits will be Purified, sometimes quickly and sometimes slowly. Below is the Biblical text to confirm these ideas:
Colossians 2:11, 13 NLT - "When you came to Christ, you were "circumcised," but not by a physical procedure. Christ performed a spiritual circumcision--the cutting away of your sinful nature. ... 13 You were dead because of your sins and because your sinful nature was not yet cut away. Then God made you alive with Christ, for he forgave all our sins."
How are we made alive? Above, the Sin Nature is cut out and removed, and below, that Old Nature is replaced by the New Nature, the Divine Nature of Christ. And it is through this Circumcision of Spiritual Flesh that we escape corruption.
2 Peter 1:4 NLT - "And because of his glory and excellence, he has given us great and precious promises. These are the promises that enable you to share his divine nature and escape the world's corruption caused by human desires."
We are Enabled to escape corruption itself (now reborn of Incorruptible Seed) . . . this is not something we choose, but are Enabled to do. Ezekiel 7:13 confirms that no one can make themselves Holy. This means that no one can choose the correct Path, but must be enabled to do so. Here are a plethora of translations for verse 13 (this is pretty amazing):
Part b of verse 13 clearly proves that no man can cleanse his own heart.
[Eze 7:13 KJV] "For the seller shall not return to that which is sold, although they were yet alive: for the vision is touching the whole multitude thereof, which shall not return; neither shall any strengthen himself in the iniquity of his life."
[Eze 7:13 NKJV] "For the seller shall not return to what has been sold, Though he may still be alive; For the vision concerns the whole multitude, And it shall not turn back; No one will strengthen himself Who lives in iniquity."
[Eze 7:13 NLT] "Even if the merchants survive, they will never return to their business. For what God has said applies to everyone--it will not be changed! Not one person whose life is twisted by sin will ever recover."
[Eze 7:13 ESV] "For the seller shall not return to what he has sold, while they live. For the vision concerns all their multitude; it shall not turn back; and because of his iniquity, none can maintain his life."
[Eze 7:13 CSB] "The seller will certainly not return to what was sold as long as he and the buyer remain alive. For the vision concerning her whole crowd will not be revoked, and because of the iniquity of each one, none will preserve his life.
[Eze 7:13 NET] "The customer will no longer pay the seller while both parties are alive, for the vision against their whole crowd will not be revoked. Each person, for his iniquity, will fail to preserve his life."
[Eze 7:13 DBY] "For the seller shall not return to that which is sold, even though he were yet alive amongst the living: for the vision is touching the whole multitude thereof; it shall not be revoked; and none shall through his iniquity assure his life."
It is impossible that Salvation is our free will choice. Impossible.
