Truth.
Sincerity in action, character, and utterance.If you're not living truth, you're wasting your time. Truth is the ultimate goal of life, but life shares little of it with us. We must search, study, dig, and observe, for the fragile signs of this truth we seek. Laws, morals, rules, and such can not reveal it, yet we know this truth when we see it. It is within us, a pattern of God's truth -- love. Take the truth you know today and live within it, tomorrow will reveal more truth for you to live within. In this manner shall you become free.
"The truth shall set you free."
The Bible.
