G.K.Chesterton saying "I felt grateful, though I hardly knew to whom," that is a reference to his original state of atheism. He said he became Christian, not by reading the bible, but by reading atheists because in their writings he recognized God's silhouette. It reminds of the writer Julian Barnes who says, “I don’t believe in God, but I miss him.” Barnes speaks to the universal longing for a source goodness, love and beauty outside of self. Chesterton’s journey to Christianity started with his desire to find a mooring for his wandering gratitude.
