All the world’s religions — so many of them represented here today — start with a simple question: Why are we here? What gives our life meaning? What gives our acts purpose? We know our time on this Earth is fleeting. We know that we will each have our share of pleasure and pain; that even after we chase after some earthly goal, whether it’s wealth or power or fame, or just simple comfort, we will, in some fashion, fall short of what we had hoped. We know that no matter how good our intentions, we will all stumble sometimes, in some way. We will make mistakes, we will experience hardships. And even when we’re trying to do the right thing, we know that much of our time will be spent groping through the darkness, so often unable to discern God’s heavenly plans.
There’s only one thing we can be sure of, and that is the love that we have — for our children, for our families, for each other. The warmth of a small child’s embrace — that is true. The memories we have of them, the joy that they bring, the wonder we see through their eyes, that fierce and boundless love we feel for them, a love that takes us out of ourselves, and binds us to something larger — we know that’s what matters. We know we’re always doing right when we’re taking care of them, when we’re teaching them well, when we’re showing acts of kindness. We don’t go wrong when we do that.From President Obama's speech at the Sandy Hook vigil. Full text here.
