How about times when a new baby is born? Of course you rejoice because there is this perfect new life, but if you are living in this world then you grieve thinking about what this perfect baby will have to endure.
But we also can rejoice when someone passes - If they are Christians! This morning everyone around the world found out that Billy Graham passed. I read a quote this morning that is perfect.
"One day you will hear that Billy Graham has died. Do not believe it. On that day I will be more alive than I ever will be" - Billy Graham
He did not die, he simply passed from this life to the next. Over the next several days, weeks and months we need to keep the Graham family in our thoughts and prayers.
