Jesus’s death and resurrection built an iconoclastic world-upheaving truth that is upheld by the counterintuitive element of grace.
Jesus is existentially satisfying because he accurately describes the human condition and provides the solution. Every other system of belief is built on performance, maintenance, reward/punishment, dichotomous banner-waving division, moralism, superiority, self-improvement, and self-isolated relativism. Jesus destroys all these categories and provides a way above all ways that I have absolutely not found in any other system of thinking.
He speaks to my desperate need for self-justification. All day long, I’m justifying myself to prove I’m worthy. I am making myself better than others and comparing my weakness to someone who is weaker than me. I am in a moral race that causes me to laugh at a celebrity’s downfall or to help the poor to look righteous. Jesus destroyed this in the cross by calling us all equally guilty and all equally loved. It was never in us to justify ourselves, but only Jesus can do this.
He speaks equally to my lack of humility and my lack of confidence. Jesus had to die for my sin so I can’t be prideful: but he was glad to die for my sin so I can’t be in despair. Both are somehow true at the same time, and it’s this paradoxical union of tensions that keeps me oriented to a self-forgetting love for others and a right estimation of myself.
He speaks to my need to serve myself and make life about me. I’m set free because my life is not about me. Life is about the story of God and we’re all bit players. Imagine this sort of freedom: when you can quit living selfishly for yourself. You’re no longer enslaved under the tyrannical dictatorship of self. Imagine this sort of Gospel-shaped person who loved you but didn’t need you, because they’re not using you as a vehicle to serve themselves. They’re not killing you as an obstacle who is in the way of their desires. They’re instead seeking to love you simply because they love you and not because of what you can or won’t do for them, and this is because they are loved the same way.
You see: Every other kind of motivation is inherently selfish. It is all seeking a means to an end, one method using another for self-gain. We’re motivated by fear, by conformity, by trophies, by pleasure, by social standing: and while they might benefit a few, they really just benefit me. The love of God is entirely intrinsic unto itself, in a single direction initiated by its own essence, with nothing to gain and no reason to exist except that it does. When we understand such a love: we’re motivated by a purely one-way love to love in the same way, motivated by the reason of no-reason, because it has inherently punctured through our souls. There is no stronger force than this in the entire universe.
