Those who belong to Christ Jesus have crucified the sinful nature with its passions and desires.
If you belong to Christ Jesus, not just in word, not simply some prayer that you prayed, but if you genuinely belong to Christ Jesus, then the sinful nature has been crucified! You are a new creature. All of those old passions and desires are dead.
Of course, we are still stuck in this fleshly body, but we are now spiritually alive.
