prayer for the disabled

I've been wondering if I could be a "true" minister to a group of people that I could lead in prayer or any service of sorts. For the past several years, I've been an advocate for disabled children. I've fought the school system and even gone to court. In all, I guess I must ask for help. Help me pray for God to heal these kids (especially those very close to me). After all, what will they be able to do when we're gone and leave them alone on this earth?
