Question

Hello native English speakers.

Which of the following expressions is grammatically correct?
Which one is a noun phrase?
Which one is a complete sentence?

1.   The thing which you think will happen in the future.
2.  The thing you think will happen in the future.
(= The thing  that you think will happen in the future?)
3.   What you think will happen in the future.
4.  The thing that you think will happen in the future.

(I guess only number 1 is a noun phrase?)

Answer

All are correctly structured noun phrases. None are complete sentences.

Answer

They are equally unclear - I would phrase it  - your thoughts determine your future. What you think today will determine what happens in the future. Much clearer. The other sentences you used could lead to misinterpretation, especially in speech rather than written text.
