As a Christian, I know we shouldn't have a "canon within the canon", but I'll admit, I just can't get worked up over Ezra. I love Malachi. I could for a long time on 2 Peter. I can even find stuff in Leviticus worth reading, but try as might, I just don't see anything interesting in Ezra. Understanding that I really do see theology in really obscure places, can someone help me see what is theological about this book?
You, my friend, have a hard heart if you can't find anything interesting in Ezra. ;-)
To me, this is a picture of the joy we will have in the Lord when He brings this age to a close and we enter the age that will last forever.
The entire book tells the story of God's influence in world history even in the operation of a worldly empire. Since the Second Temple was rebuilt, Jesus was able to enter it and, ultimately, bring the Mosiac Covenant to a close.
I was reading the last page of the Catholic Catechism where it gives the abbreviations for all the books in the Bible and I noticed
My next thought was of this question and I wondered whether Ezra is referenced in the Catechism and by golly it is.

This answer is incomplete - but I'm not sure how to resolve it. It is based on a sermon I heard a long time ago. Please help make it better if you can - if not downvote or perhaps delete?
This is not an answer to the whole question, but here is one interesting lesson from Ezra. It answers the question: should we trust in God completely or allow humans to help? E.g. should we only pray for healing or allow doctors to intervene?
Nehemiah asked for and got help from the king, though he acknowledged God's hand:
By contrast, Ezra was ashamed to ask for help, so he relied on God:
So both are supported in scripture by men of faith and a God of grace.
