"The tree does not understand the pruning, nor the ground the tilling, but the husbandman knows."

I've used this expression for like 15 years now. I don't know where I read it. I use to read a lot when I was single. It may be that I read it in Spanish originally. Does anyone know where it came from? I've never found it anywhere again, nor anyone that ever heard it.

It's an answer to people who ask themselves why does God would allow suffering, hardship, wars, false religions,  whatever disturbances. God is the husbandman, and what could be worse that having our limbs hacked off, the pruning of a tree, little do we know that we will yield more fruit. etc on the tilling.
