All in the same time

I feel it would be ludicrous for me to say or even think that God's abilities are limited, or that something is impossible. Who am I to put God or his ability in a box? So, why then do we think that it could be wrong or impossible or even strange to have joy alongside heartache? Why do we doubt that possibility? In Deuteronomy 7:8 and 4:37 we see that Gods mighty power drove the Israelites out of Egypt. Why...because he loved them - its in black and white. The tower of Babel, Shadrach, Meshach, and Abednego...Gods mighty power protected them. Let's think about the cross for a minute. Lets go back to the core of life. The example we are called to live by. The one story in the bible that many Christians and non-Christians know. The story where life begins..lets go to the cross. Jesus was crucified on a cross in front of family, friends, enemies, all of the town. How do you think those who loved Jesus felt? Do you think they cried? Do you think they hurt? Do you think their hearts ached? If you have ever lost anyone, then you easily know the answer to that question is yes. If you dont and need it in black and white then look to the scriptures. In Luke 2:35 Simeon rejoices with Mary and Joseph over their child but also tells Mary that along with her joy, her heart will also be pierced with a sword - causing anguish - heartache. We also see in Luke 1:46 that Mary sings a song to Elizabeth of great joy in what the Lord has done.  How do we look at the cross, at the crucifixion, and not see the heartache? How do we look at the cross, at the crucifixion, and not see joy? Mary, mother of Jesus experienced great heartache and great joy all at the same time. So why then would we think it so odd of others to experience heartache and joy simultaneously?
