This psalm is very deep and demands a bit of research. Who are the gods, to whom is the address spoken to? how does this relate to our spiritual understanding of heaven and the world we live in.
I am not going to write my thoughts or findings as this is perhaps something that everyone should do for themselves.
It is interestingly put with Matt and Jer passages that work really well to make us consider these things more.
You could also read John 10 and Ephesians 6 with this psalm.
