In biblical times it was common to sprinkle ashes on the head as a sign of repentance and humility. Ash Wednesday marks the beginning of Lent, which is the time we contemplate our relationship with God and identify the areas in our spiritual life that need work. The ashes are a physical reminder of our Lenten journey; by receiving the ashes on our heads and keeping them on through the day, we are recognizing that life passes away on earth. Therefore we strive during Lent to turn away from sin, refocus our lives on following God's commandments, and look towards the Kingdom of Heaven.
