The essential distinction between Christianity and all other religions—including secularism—can be boiled down to one question: Who is the hero of your story?
The human race was cursed when Adam and Eve decided to be the heroes in their own story. When they took God’s place in the Garden. All subsequent sins are variations on that theme: we are usurping God’s place.
But Scripture says that real fruit, the fruit that endures for eternity, is fruit that brings glory to the Father. It makes him the hero; God’s power shown through our weakness. And it’s always been that way.
