And if your are purified by Christ on what basis can one possibly presume to affect the duration or difficulty of a process which is in CHRIST' hands?
Because your righteousness is already complete.
Therefore if any man be in Christ{present perfect tense], he is [present tense] a new creature: old things are passed away [past tense]; behold, all things are become new [present perfect tense]. And all things are of God, who hath reconciled us [past tense] to himself by Jesus Christ, and hath given to us [past tense] the ministry of reconciliation; (2 Corinthians 5:17-18 KJV)
So if you are in Christ, you are reconciled unto him. Now! Not later. Now. There is no future punishment for your sins. No matter how wretched you see yourself, you have been reconciled unto him. You are not defiled because Christ has made you righteous through faith.
It always amazes me how the Roman Catholic Church seems to ignore wholesale the teaching of the Book of Romans. But one cannot really read the Book of Romans and not walk away knowing that if you have faith in Christ that the only thing awaiting you after death is Life. Abundant life. No more suffering and no more tears.
Those who teach Purgatory teach another gospel. Sorry, but it is ANOTHER Gospel.
