For believers earth is a prison,
How interesting that you liken earth to a prison.
Is earth the prison, or just the 'prison yard'?
After all we the living are not yet locked up or shut up in our prison cells [graves]
We are all shacked in death's prison precinct. But we do have partial liberty now while we await for deliverance from our death sentence. [ Ezekiel 18 vs 4,20]
We are still walking around in the prison yard.
Because Jesus died a hero's death that means that sin and death will not always continue to reign on earth.
Not because we can be innocent, but Just as a Judge can pardon a person so the crime [sin] charges no longer stick,
Jesus has full power or control over the 'great prison house of death' to pardon us.
Those of us still alive at the soon coming 'time of separation' of Matthew
[25 vs 31,32] will be issued No death warrant, No death watch, but we have hopes that we will not die but remain living into Jesus 1000-year reign over earth.
Remember Satan (our great jailer] does Not have the keys to death's cell door.
Jesus has those keys [Rev. 1 v 18]. Keys to unlock death's prison house of detention so that the humble 'sheep'-like people on earth can remain alive on earth right into the start of Jesus millennial reign over earth, when Jesus ushers in global Peace on Earth among men of goodwill, with everlasting life in view on a paradisaic earth forever.
-Psalm 72 v 8
