Many Christians backslide...They are unable to stand against the temptations of the world, or of their old nature. They strive to do their best to fight against sin, and to serve God, but they have no strength. They have never really grasped the secret: The Lord Jesus will every day from heaven continue His work in me. But on one condition-the soul must give Him time each day to impart His love and his grace. Time alone with the Lord Jesus each day is the indispensable condition of growth and power.

I've realised over the years I play my best when I have time to prepare for each tournament as best as possible.

It's always nice to get good feedback, and a bit of encouragement can go a long way.

Abide in Jesus, the sinless One - which means, give up all of self and its life, and dwell in God's will and rest in His strength. This is what brings the power that does not commit sin.

In tennis, it is not the opponent you fear, it is the failure itself, knowing how near you were but just out of reach.

People think I am unemotional because my voice is flat and a bit boring. It is unfortunate but it is just the way it is. I've tried to change it but it doesn't seem to make a difference. The truth is, I have lots of emotions inside. I cried after the semi-final at Wimbledon [2012] because I was proud to reach the final and I knew how much it meant to the country. I cried after the [losing] final [to Federer], too, for different reasons. I felt I had let people down. I think people warmed to that. They could see how much it hurt.

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.
