Without having faith in oneself you cannot move a step forward in life. Second, without having faith in society, you will not be able to live and co-exist in society. And thirdly, without having faith in the Divine, life can never be complete. It is important to have all these three kinds of faith in life.
A Christmas tree bears the gifts and the lights not for itself. Similarly, all the gifts (Talents) you are carrying in your life are for others. Anyone who comes to you, offer them your gifts. When you show kindness, your true nature comes into play. Also remember that like how christmas tree leaves are ever green despite storm or snow, your life is evergreen and your spirit is eternal despite personal and social grief.
