Are Christians Supposed To Be Happy All The Time?

In this episode, Dr. Betters answers the question, "What does "who for the joy set before him endured the cross mean from Hebrews 12?" I have heard Christians use this and other verses about joy to say we need to be happy all the time. But that is just not what I feel. It makes me not want to go to church when the theme always seems to be "be happy" even when life sucks.”
