Many months ago, I was seeking and praying about the nature of God and I found A W Pink's 'The Attributes of God'. It's a short but dense book.
Quick quotes: "The infinite knowledge of God should fill us with amazement."
"The mercy of God has its spring in the divine goodness."
Among numerous other gems.
It can be found on SI, chapter by chapter. Or free/99 cents on Amazon.
Here is the book for free with a study guide
