I have no more "MASSIVE" problem with Lk.16 than with Isa.59:1,2 and Rev.21:21 etc., etc.
God bless.
Behold, the LORD’s hand is not shortened, that it cannot save,
or his ear dull, that it cannot hear;
2 but your iniquities have made a separation
between you and your God,
and your sins have hidden his face from you
so that he does not hear. Isaiah 59:1-2
Clearly, God does not have a face or hands or ear. God the Father is invisible, and cannot be seen, nor has he ever been seen according to Paul. These are metaphorical as I mentioned earlier, as representing that God has the power to save and they are not beyond his reach. That he is able to hear their pleas for help, but that it is because of their sins God's face has been hidden from them. This metaphor isn't describing that God has hidden his face from them on account of their iniquities, but their sins and iniquities have acted like a dark cloud that has separated them from the gracious favor of Yahweh.
This is clear and consistent metaphorical language used in the OT.
In regards to Revelation 21:12, context is in order..
Then I saw a new heaven and a
new earth, for the first heaven and the first earth had passed away, and the sea was no more. Revelation 21:1
The events described in Revelation chapter 21 are taking place in the PHYSICAL realm, the new heavens and new earth, and the city of Jerusalem will be there we see in v.2 and the description in v.12 is describing this city, on the physical planet earth that has been restored.
Do you believe the events in Luke 16 are metaphorical? Or does it change from a description of a literal event, to a metaphorical representation of the intermediate state?
