  • Personal Philosophy

    The heavens declare the glory of God;
    the skies proclaim the work of his hands.
    Day after day they pour forth speech;
    night after night they reveal knowledge.
    They have no speech, they use no words;
    no sound is heard from them.
    Yet their voice goes out into all the earth,
    their words to the ends of the world.
    --Psalm 19:1-4 (NIV)
