What are some words of comfort for someone who has been in a serious accident?

I might try finding Nave's Topical Bible at a library or bookstore, and you can find passages of scripture under certain topics such as "comfort," or "tragedy," or "pain." Also, you can type those Words into www.blueletterbible.org, and it may have some scripture selections for you. Mention that God thinks that he or she is so special that he wants them to rely on him now, and get close or closer to him. Sometimes, God will use what he can to accomplish his purpose in us. Our comfort is not so important to God as our character is. God's strength is made perfect for us in our weakness.
