The Guest of a Great Sinner

Sometimes, we wonder if we have true faith that saves our souls. We wonder: do we truly have a relationship with God? Yes. We believe that Jesus died on the cross for our sins and rose from the dead. We believe that he ascended into heaven. Yet when we look at our lives, we find little change. We find little love for God. We find bible reading stale. Our prayers seem rote. Our love for others has grown cold. How do we know that we have true faith? How do we know if we have invited Jesus into our lives as an esteemed guest?
