Yes, there IS something left to do...
"For our conversation is in heaven: from whence also we look for the Saviour, the Lord Jesus Christ: Who shall change our vile body, that it may be fashioned unto his glorious body, according to the working whereby he is able even to subdue all things unto himself." Philippians 3:20,21.
Does this happen over time, in purgatory, until we are acceptable to enter heaven?
"Behold, I shew you a mystery: We shall not all sleep, but we shall ALL BE CHANGED, IN A MOMENT, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be CHANGED." 1 Cor. 15:51,52. It's not a process. It happens in the twinkling of an eye.
That’s the most telling counter argument yet. Thanks.
