They’re on their way to Mars, there is only enough for the 3 of them and then they find him. And in the process of finding him, a vital piece of the spacecraft breaks meaning less oxygen, and the captain gets injures. Crazy! I won’t give too much more away, a decision has to be made, and Zoe ends up making a huge sacrifice.
This reminded me of Jesus. We were trapped in our sin with death being inevitable. But Jesus dies in our place, takes away our sin, and gifts us eternal life. We just need to say yes to Him.
