Unpacking faith

Guy Plowman: "I have faith in science because it has been consistently useful in helping me to navigate the physical universe." 

Don't you have instead confidence in Science? I think sometimes we overuse the word 'faith'. Eg, I don't have faith in my wife, I trust her. I don't have faith in my daughter's future, I hope she'll do fine. I prefer to reserve 'faith' where it's used to describe that belief that gets stronger especially when the evidence is overwhelming against it. Let me quote Jesus on this one: "I assure you, if you have faith and don't doubt, you can do things like this and much more. You can even say to this mountain, `May God lift you up and throw you into the sea,' and it will happen." (Matthew 21:21) That's the faith I'm talking about!
