A lot of my favourite Star Wars lines are about the Force.

“My ally is the Force, and a powerful ally it is. Life creates it, makes it grow. Its energy surrounds us, and binds us… luminous beings are we, not this crude matter! You must feel the force around you: between you, me, the tree, the rock, everywhere… yes, even between the land and the ship.” - Yoda, TESB

“Rejoice for those around you who transform into the Force.” - Yoda, ROTS

“The island. Life. Death, and decay… that feeds new life. Warmth, cold, peace, violence… balance. An energy. A Force… and inside me, that same Force” - Rey, TLJ

And if I may expand it beyond just the movies…

“It matters which side we choose. Even if there will never be more light than darkness. Even if there can be no more joy in the galaxy than there is pain. For every action we undertake, for every word we speak, for every life we touch - it matters. I don’t turn towards the light because it means someday I’ll ‘win’ some sort of cosmic game. I turn towards it because it is the light.” - Qui-gon, Master and Apprentice

“The Jedi teach that life doesn’t cease at death, but merely changes form in the Force. Your parents are alive inside you, Ezra. They will be… always.” - Kanan, Rebels s2 ep10

Obviously I have more, but these are just ones focused on one theme for now.
