Doorposts Reviews? Character Building/Bible?

Is anyone here familiar with Doorposts? For Instruction in Righteousness? Plants Grown Up? Polished Cornerstones?

I'm curious about these books and want to know more about them!

Or maybe recommend me different Character Building/Bible materials that you've enjoyed!

 

I have those exact books but I do have a couple of things from Doorposts. I like them a lot.
