Romans 6:5-6

Romans 6:5-6. For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection: Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.

There has a death taken place in us, and though there be relics of corruption still alive, yet they are crucified: they will have to die, they must die they are nailed fast to the cross to die in union with the death of Christ.
