I can't find the source right now, but the meaning of "si spiritus pro nobis, quis contra nos?" is that if the spirit [of the people] is with us, then who can oppose us? The context is that of a revolution or a constitution or something, I forget, but in a revolution, clearly nothing can stop the combined will of the people, and so they should have nothing to fear. If all the people want something or to live in a certain way, who or what is there to oppose it?
