For me it is more than symbolic that my mother passed away between resurrection Sunday and Ascension Day - she left us and reminds us that we remain here between these two pillars of existence. So how did Jesus' followers feel after they saw him bodily go up into the sky? They had been together with him for about 3 years almost daily. But I knew no life without my mother somewhere, near or far, still playing an important role in my life. Now I have to find a life between resurrection and ascension, a life in which I remember her and anticipate seeing her again.
Help has come from different sources. The Bible and prayer play primary roles. A little book by N.T. Wright, "Following Jesus, Reflections on Biblical Discipleship" has been very helpful in clairifying misunderstandings about life after this life. And a CD I seldom heard has reminded me that for Christians, when we see God directly and see our family and friends again, knowing there will never be a separation ever again, it is a time, an existence of matchless joy and celebration, described in the Bible as a giant feast with the best foods and wine and lots of dancing. In other words, you cannot imagine having a better time. And all our family and friends who have passed out of this life now enjoy this feast, and they also long for us to join them, and they know we will join them, sooner or later.
So for me, this time of waiting is a part of the "sting of death" Paul talks about in 1 Corinthians 15, the emotional grief and pain of separation that should also remind us: this is the last thing that God will remove, and then it is all over. No more pain, grief, separation, tears, fear, insecurity, or wondering what will happen.
