Why does the bible say a man returns when he dies? It means he has a place to go back.
So, where does he return? It is the kingdom of heaven.
In fact, all people were angels and lived in heaven, but we have sinned and paying for that in a prison called Earth.
God said we would return to heaven but there is a very important condition.
Even if we have our spiritual hometown however, if we don't meet the condition, we can't go back.
We must receive the tree of life our sins can be forgiven and that is the Passover.
In other words, only those who keep the Passover can return to our spiritual hometown, the kingdom of heaven.

[Hebrews 11:13-15]
All these people were still living by faith when they died. They did not receive the things promised; they only saw them and welcomed them from a distance. And they admitted that they were aliens and strangers on earth. People who say such things show that they are looking for a country of their own. If they had been thinking of the country they had left, they would have had opportunity to return.
