Your second sentence doesn’t follow from your first.
I’ll tell you what. You go to Heaven with your sins “covered” and I’ll go with mine purged and we’ll see who has a better time.
Purgation is the process whereby we are made clean, because of the Blood of Jesus. Not “covered”. Who would want to be covered when you can be changed?
Your problem is if you are awaiting purgation, you’ll never make it to heaven. Either all your sins were forgiven and remembered no more by the finished work of Christ on the cross, or none of them were and you’ll remain dead in your sins. Your ransom will not have been claimed and there remains no other sacrifice for your sins.
