"To live without faith, without a heritage to defend, without battling constantly for truth, is not to live but to 'get along'; we must never just 'get along.'" - Blessed Pier Giorgio Frassati
I am so glad you asked that question. So often I read and hear similar accusations against the Jews, without realizing Christians are in a similar danger. St. Paul talks about that as well in his letter to the Romans (chapter 11 specifically).
A very good personal question. If only we would each as individuals really let it sink in, that very almost incomprehensible love God has for us. God desires to give Himself to us at the personal level and we are forever saying, "No thanks."
