Consider heavenly as a person (5)

I believe the answer is:

deify

I'm a little stuck... Click here to teach me more about this clue!

'consider' is the definition.
The definition and answer can be both related to thinking as well as being verbs in their base form.

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" .)

I've seen this clue in the Evening Standard.
