The Challenge and Conquest Youcat number for December is about heaven which is very appropriate for Christmas, as it is a time of hope.
#52 What is heaven?
Heaven is God’s milieu, the dwelling place of the angels and saints, and the goal of creation. Heaven is not a place in the universe. It is a condition in the next life.. If with God’s help we arrive someday in heaven, then waiting for us will be “what no eye has seen, nor ear heard, nor the heart of man conceived, what God has prepared for those who love him.”
