Wiki defines hope as: the emotional state, the opposite of which is despair, which promotes the belief in a positive outcome related to events and circumstances in one's life.
I have hope that my son will walk again. Because if I didn't have hope that means I expect him to never walk again. While he might not, I refuse to give up. He deserves more than just for me to say its too hard, too painful, too heart wrenching.
I have hope he will go into remission because the alternative is well...just too awful to imagine. I refuse to see my son's cancer take him. I know its possible, we are battling a deadly disease. That left to its own would mean sure death. But I have hope, I have to have hope. For him I have to have hope, for his brothers and sisters.
I have hope, not despair, for the future. That there will be positive outcomes in all the events and circumstances in my life.
