Consider heavenly as a person (5)
I believe the answer is:
deify
'consider' is the definition.
The definition and answer can be both related to thinking as well as being verbs in their base form.
Maybe there's an association between them I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for deify that I've seen before include "Exalt to godhood" , "Make godlike" .)
