Mateo's statement will last because it does not purport to know the answers. is not certain about anything, has no fear of the doubt that precedes faith, and does not look away from the world's pain. That uncertainty has opened him to God. Contrast Mateo's statement with so many of the comments which too often proclaim a fearless certainty about
God, pretend that faith rids us of doubt, and rationalizes the world's pain.
Your purpose is what God has put in front of you at this moment - big or small - and no one has the right or ability to judge it.
