Is it bad I don’t find God merciful?

[Hawkins]

Not to say I am an atheist or a non believer but just reading a good portion of the Bible, I don’t see much mercy. Most people who are sinned are punished and most areas that are sinful are destroyed minus a few like Nineveh. For the most part the Bible (especially OT) is a book of wrath. I believe God is real but not merciful

I think you first need to understand what a shepherd is. A good shepherd shows mercy to his sheep but not necessarily the wolves. He won't hesitate to kill the wolves if they try to harm his sheep.

God's mercy is to bring salvation to humans. This cannot be done without Israel being correctly established, spiritually speaking. God's wrath mostly are done for the establishment of the correctness of Israel such that His salvation can reach today's humans. Or else mass of today's humans will have to wind up in hell.

That's where God's mercy is.
