So a few comments on this statement that I've been thinking about recently:
I can't know the Truth: My brain can't understand everything! And it will never be able to understand everything and was never designed to! I don't know correct answers. I can only offer my unique perspectives on the world built from my unique experiences.
But I can know the Truth: But I can get to know and build a friendship with the boss and creator of the universe, who is Truth.
