Joni is a talented artist and at her first exhibition she meets a Vietnam veteran who is now struggling with the loss of his eye and his hand. I know who put me back together. If there really is such a place as heaven, and Jesus really died on that cross because he wanted to bridge the gap between God and us, then getting to know him and all that means, should be worth looking into. I'd rather be in this chair knowing him then on my feet without him. And, in that moment Joni knows that she has been found the meaning of her paralyzes.
Tragic events happen.
God does not cause them to happen. Through Christ, pointless tragic events are given meaning. Meaning is attributed after the tragedy. By choosing Christ, our lives become meaningful because of Christ. God's gift to us is meaning where there is there is hopeless.
