Faith is important. Whatever your spirituality is (including atheism), believing in something that grounds you is important. Maybe family. Or community. Maybe health. Or career.
Obviously, faith was important to Jesus. He said if you believe in what I represent you will do amazing things.
What do you have faith in? Does it make your life better? Easier? Does it challenge you to leave your comfort zone, or encourage you to stay put.
What do Christians have faith in? Could it be true that through it they will do amazing things?
