Who is God, and how can we find him? One answer to this question is that something of the light of God already lies deep in each of our hearts. At times, this is to be felt only in a deep longing for goodness, justice, purity, or faithfulness. But if such a longing turns to faith, we will find God. The early Christians said that if we seek God we will find him, because he is everywhere. There is no boundary that cannot be crossed, no hindrance that cannot be overcome, to find him. We cannot excuse ourselves for not finding faith. If we knock at the door, it will open.
