Truth.
It is the most elusive of all things to us yet it is right there desiring to be embraced. I think we, humans, make it difficult. We obscure and seek to run from truth because it frightens us. Pontious Pilate admitted his own skepticism regarding truth when he asked Jesus – Τί ἐστιν ἀλήθεια – "what is truth?""
I found a great quote I want to share with you on truth:
"It is a beautiful and terrible thing, and should therefore be treated with great caution."
