I tend not to argue about things that I don't believe in.

There is need of a great revival of spiritual life, of truly fervent devotion to our Lord Jesus, of entire consecration to His service. It is only in a church in which this spirit of revival has at least begun, that there is any hope of radical change in the relation of the majority of our Christian people to mission work.

I proved that I can win the Grand Slams. I proved that I can last four and a half hours and come out on top against one of the strongest guys physically that tennis had probably seen especially on this surface. So they would probably be the things that I would say I have learned tonight: To not doubt myself physically and mentally from now on.

For me the most important thing has always been tennis, and that's what I want to get across the image I want to portray is a hard-working tennis player.

For me, by far, the Olympics is the biggest sporting event in the world.

I'm incredibly fortunate and it's important to me to make sure that I give back where I can.

I think most players would love, at one stage in their career, to say, 'I've been No. 1 in the world.
