As most of his books did to me, it made me cry. But more so, it really inspired me. This is actually a story of two very different men but the same in a lot of ways. And basically, it's about faith. :]
I learned that, it doesn't matter what your past was-- who you were or how you did-- what matters is the now, and how you are living it.
Never let other people's past be the basis of how you see them today. People can actually change for the better and we just have to open our minds & hearts to them, because they might just turn out to be the very people who will inspire us to be a better individual. :)
