Truth Vs. Truthiness

Even at His trial, Jesus boldly tells the truth.  I remember reading this when I was younger and wondering why He didn't just plead the fifth.  Why say anything, since it will incriminate Him in their eyes?   Because He Who is the truth will not hide the truth.
I tend to be cagey when confronted.  I won't tell an out and out lie, but I'll only tell the portion of the truth I am willing to be let known, which sometimes seems to be the same as a lie (also known as "truthiness".  I'm talking about times it benefits me, not just when it keeps from hurting someone else.  I still think there is nothing wrong with telling a woman that you like her old hairstyle better, rather than coming out and saying she is to old for a faux hawk.   I mean when I say I didn't call back because I've been "busy with Church stuff", rather than saying that I've just ben neglectful and putting other things ahead of friendship or family.
But Jesus IS truth, and any rejection of the truth is in the long run a rejection of Him (faux hawks not withstanding).
Juxtaposed in the scripture I read today is Peter's total deny of even knowing Jesus.  
*SPOILER ALERT*
We will find later that Peter is forgiven by Jesus.   He who is truth forgives Peter, which makes him truly forgiven.  The truth is stronger than the lie.
