I have often wondered what is the meaning of the following bible verse: John 8:32: and you will know the truth, and the truth will set you free. (ESV) It seemed a very strange preposition. Know the truth, and the truth will set you free. If truth were a physical object, like a sword, I would have thought, it means, learn using the sword, and it will set you free. However, I thought, truth is just an abstract concept of mind.
