Jean Paul Sartre wanted to be remembered fighting for causes of humanity around the world. This is quite ironic because he and his cohorts espoused existentialism, a philosophy which can affirm no other reality other than self-existence and self-affirmation.
Our modern world, without even knowing the profundities of philosophy, has basically adopted the existentialist outlook. But people largely haven’t caught on to helping others. You see, if all you can really know is between your ears, then you can live for yourself, please yourself, serve yourself, because you don’t even know if others exist, much less God.
The Bible is antithetical to all this non-sense. Nobody should seek his own good, but the good of others. — 1 Cor. 10:24 NIV. If you exist, you DON’T exist for yourself but for others.
When I was in high school, my teachers indoctrinated me with existentialist teaching. It troubled me. As a youngster, I still didn’t have depth or perspective to see through the veneer of sophisticated arguments. I’m glad I held on to Jesus through the years.
Not so, many friends. The onslaught of teaching evolution, Marxism, existentialism and the like was the fusillade they didn’t survive. Those authors and teachers pointed students to a “reality” void of any purpose other than self-actualization.
Christianity does many wonderous things for you and to you. But eventually you are to mature and join Christ’s work in helping others. When you get to that point, you will discover the greatest happiness humanity can know: the satisfaction of serving God and people. Stop focusing on your self.
