This will blow your mind. The human mind has no capacity to reason to truth. Without truth, rational thought is impossible. Without truth, we would be like brute beasts reacting to our five senses and trying to survive by what seems to work but never coming to any rational conclusion about anything. Of course, it’s not necessary to live without truth. You just have to know a Person Who knows all things, can’t lie, and is willing to share Truth with you. That Person exists and He is knowable. In Him is hidden all wisdom and knowledge.
