The large male face to the left would be Seraiah's, as the angel leading us, which is also symbolic of the Angel that led latter day Moses and Aaron.
The light in Chosen is the light of Christ's message - Truth - shining brightly for all to see. The white fiery look to it also made me think of Seraphs helping to light the way for us, and also Father, who oversees everything and who's plan is unfolding before our eyes.
To the left I also see many people - some looking towards the light and some looking away. It was hard to tell if they were representing latter day or modern day Israelites. The message seems to combine the two stories. The latter day story and the modern day story of Moses, Aaron and the Israelites.
Two warriors also stood out. What kind they were, I'm not sure... but they could represent the Egyptians as well as those in the modern day who seek to snub out the light of Truth that has been revealed through Father's book.
To the far right, the arched structure looked to me at first glance like a bed. It could represent rest, or, "putting something to bed". It made me think of being in the final stages of Father's plan in regards to the Tribulation and coming Armageddon. Another thought was that it could represent the Rapture Vessel door (or gangplank - I'm not sure what it's called), which is still open and still receiving of those who choose to accept Christ and Truth. I could also see it as being a clock, perhaps saying that while time is running out, there is still time left too.
