For me, personally, the most difficult moments had to do with not just terrorist attacks, but also shootings.

I'm not somebody who is always comfortable with language that implies I've got a monopoly on the truth, or that my faith is automatically transferable to others.

So I came to my Christian faith later in life, and it was because the precepts of Jesus Christ spoke to me in terms of the kind of life that I would want to lead. Jesus Christ dying for my sins spoke to the humility we all have to have as human beings, that we're sinful and we're flawed and we make mistakes, and that we achieve salvation through the grace of God.

That is the story of our history - whether it's the pursuit of prosperity for our people or the struggle for equality for all of our citizens, our commitment to stand up for our values abroad, and our sacrifices to make the world a safer place. Let us remember that we can do these things not just because of wealth or power, but because of who we are. One nation under God, indivisible, with liberty and justice for all.
