As is my bent, I couldn't help but see the gospel intertwined in the story (albeit unintentional). If you've seen the move, read on. If not, there could be some spoilers below, so be warned.
Cooper was used to save mankind, and although he was not a perfect man, like Jesus, he did make his decisions based on all of humankind, not just his family. While physicists, astronauts and engineers mathematically argued what should be done based on numbers, Cooper argued that there was only one option...save mankind. When God sent His Son, He didn't have to, and He made that sacrifice for all the generations to come. Nothing made sense logically to the way Jesus came, lived or died (and rose again), but it was all part of the plan. I will say that humankind was spared in the movie. You'll have to watch it to see how.
One of my favorite lines from the movie was spoken by Brand. She was played by Anne Hathaway and was the daughter of the physicist solving the equation for gravity. Without going into detail regarding the genesis of this quote (because it would take too long), Brand defends why she believes the team should choose to return to one of the three planets. Love. The astronaut supposedly there was her true love. With little to no evidence about the status of the three planets' astronauts, other than a blip that that were alive, she felt drawn to that planet. Her quote was "Love is the one thing we're capable of perceiving that transcends time and space." Powerful.
Scripture teaches us that God is love. And although our finite minds can't perceive the fullness of who He is, He has made a way for us to experience that love through His Love through us in Jesus Christ. This quote stuck with me...."that transcends time and space." God is bigger than time or space. He never slumbers. He is omniscient. He is love. As a new year begins, it is good to know that the Creator of this universe is concerned with loving me.
