-Everyone does not have their own truth. We all know there is one truth.
God is infinite, we are not, therefore any perception of truth in a day-to-day life is inherently flawed. The truth is far grander than we with only five senses could perceive. Only when God decides to meet us half-way do we truly see. You may claim this has happened to you, and I will not argue for God lies only as far as your heart. But if you think that such an experience imparts some sort of "truth-sense" you are mistaken. There are no absolutes in a universe of change. For a truth-seeker, hubris is like a yoke. Humility is the path of virtue, never assume you know anything.
As for this crap about not having our own truths, I think I'm not sure what you mean. Do I know what this truth is but am just not willing to admit it to myself? Why do you have all the answers, for that matter why does the bible?
