We are not *imperfectly purified*.
We have the righteousness of Christ credited to our account. We are as pure as we need to be.
Those who are born again, born of the Spirit, have a NEW nature, one that does not sin. When the body of flesh dies, all that is left is the perfected in Christ new nature.
We don’t take the flesh with us so there’s no need for cleansing from it.
We are not *imperfectly purified*. We have the righteousness of Christ credited to our account. We are as pure as we need to be. Amen! How anyone can think, much less teach, that the righteousness of Christ imputed to our account is somehow "imperfect" is ridiculous. We are not justified by our works, but by the blood of Jesus Christ which cleanses us from ALL sin. Jesus is our place of purgation, our place of cleansing from ALL sin. The law of Moses could never make us righteous, neither could the blood of bulls and goats offered upon the Mercy Seat in the Temple. BUT...
But when Christ came as high priest of the good things that are now already here, he went through the greater and more perfect tabernacle that is not made with human hands, that is to say, is not a part of this creation. He did not enter by means of the blood of goats and calves; but he entered the Most Holy Place once for all by his own blood, thus obtaining eternal redemption. The blood of goats and bulls and the ashes of a heifer sprinkled on those who are ceremonially unclean sanctify them so that they are outwardly clean. How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God!
For this reason Christ is the mediator of a new covenant, that those who are called may receive the promised eternal inheritance—now that he has died as a ransom to set them free from the sins committed under the first covenant. (Hebrews 9:11-16)
