Jesus said, “Whoever tries to keep their life will lose it, and whoever loses their life will preserve it” (Luke 17:33). It is a paradox, that we lose our lives in trying to save them, but gain them in giving them up. We are broken, usually focused only on ourselves. It is only in giving everything for another that we can truly be alive.
All life feeds on death. If it were not for the death of other living things every day, we would not remain alive: whether it is a cow to provide the hamburger for lunch, or the wheat plant or the lettuce and carrots for the salad, living things gave everything for us. Likewise, Jesus gave everything so we could live.
