QUESTION! PLEASE HELP!

So, regrettably I have a bunch of questions regarding this movie due for a class, and since we didn't have the questions WHILE watching the film, I wasn't looking for specific things... so if anyone has it and knows anything about these instances, PLEASE help me!! Thanks in advance.

How does Joshua define "hope"?
According to the movie, who brings "hope" into people's lives?
How does Joshua define "love"?
How did Joshua help Kevin, besides teaching him guitar?

If anyone could offer any direct quotes from the movie or just some examples with which I could form my answers around, I would REALLY appreciate it!
