Gnosticism and non-canonical texts

i was all over the place with this one.... my bad 😂
is it possible for god to have divinely inspired works that are not included in the Biblical canon?
is it possible for a human to write something that is complimentary to christianity such that it would improve your faith by reading it?
if the answer is yes to either of those questions, it could be very beneficial to begin reading non-canonical texts.... even just to spice it up a little!
