I too have asked these questions. One song that replies to these questions: Matt Maher sings "You were on the cross".
Lost, everything is lost
And everything I've loved before is gone
Alone like the coming of the frost
And a cold winter's chill in my stony heart
And where were You when all that I've hoped for?
Where You when all that I've dreamed?
Came crashing down in shambles around me
You were on the cross
Pain, could you take away the pain?
If I find someone to blame, would it make my life seem easier?
Alone, all my friends are asleep
And I can't find anyone to stay awake with me
Where were You when sin stole my innocence?
Where were You when I was ashamed?
Hiding in a life, I wish, I never made
You were on the cross, my God, my God, alone, alone
You were on the cross, You died for us, alone, alone
You were on the cross, victorious, alone, alone
You were there in all of my suffering
And You were there in doubt and in fear
I'm waiting on the dawn to reappear http://www.youtube.com/watch?v=ZCPsZ-Vi6Ck
