How is it that we can hold sorrow and joy at the same time?

That question has been with me these days...as I listen to so many people through the day, which is my blessing and privilege, I note how each life is called to do this and how hard it can be. How do you experience this in your life? Do you think God made us this way...to hold both pain and joy at the same time within us? Do we hold them in the same place within or in different places within? Is our goal to "get rid of the pain" and just be joyful? Is that possible? Is that our life goal which brings that peace the world cannot give? What was Jesus' experience of this human phenomenon? Come on in, I love your conversations....God's Peace, your sister with heart:)
