What would happen if Donna never met the Doctor? How would Earth handle the Racnoss, the falling Titanic or the Sontarans? In this episode Turn Left (Series 4/11), the question is answered. Aided by a familiar blonde time traveller back from a parallel universe (Rose), Donna travels through time to stop the alternate time line from happening, sacrificing her life (or at least one version of it) in the process. All it took was a simple turn left at a certain intersection, at a certain time on an ordinary day.
Donna was probably the most fiesty of the Doctor’s recent companions. She was never scared to challenge his decisions or let him know that she was not remotely interested in the “long streak of alien nothing” that he was to her. She just wanted a mate, an adventurous travelling companion. And he was certainly that. She wanted to travel with him forever. But it seems she was more brilliant, more important, than she or we ever knew. At the end of this episode we realise that without Donna meeting the Doctor, he would not have survived the battle with the Racnoss, and so many more alien encounters would have ended in disaster for humanity.
The Doctor: Sometimes I think there’s way too much coincidence around you, Donna. I met you once, then I met your grandfather, then I met you again. In the whole wide universe, I met you for a second time. Like something’s binding us together.
Donna Noble: Don’t be so daft. I’m nothing special.
The Doctor: Yes you are, you’re brilliant!
Rose Tyler: [Donna has a flashblack] I thought you’re brilliant.
Donna Noble: She said that.
The Doctor: Who did?
Donna Noble: That woman, I can’t remember.

In the same way once we enter this world it may not take long for us to become fully convinced that we are totally insignificant. Most people think their lives are just a random collection of incidents or accidents and that there is no one is watching or concerned for their future. John 3:16 and Ephesians 2:10 tells us something quite different. We are worth rescuing (God sent his Son into the world to save us) and God has planned in advance for us to do great things in His name. If we are His, if we belong to Him, no insignificant moments go by. All things are being worked together for good, and He is willing to use us in His plan. We may not get to stop the universe from imploding (like Donna), but certainly God’s work through us will be brilliant!
