I'm doing a calligraphy canvas piece for someone and I just wanted to check I've got a grammatically correct translation into Latin.

It's a quote from Paulo Coelho's 'The Wich of Portobello'

God hid the most important things from the wise because they cannot understand what is simple

Dues celo quo sapiens plurimus magnus res
Quoniam non conspicio illa quae est directus

Thank you very much to anyone for your help.
