"Fortunate Fall"
O happy fault - o happy fault,
That gained for us so great a Redeemer.
Fortunate fall - fortunate fall,
That gained for us so great a Redeemer
This theology, held by the likes of St. Augustine and Thomas Aquinas, has fallen out of favor: that God allowed bad in order for something even better to happen. And maybe it is just that it has fallen from favor, but regardless it highlights the beauty of our redemption.
Redeeming our sin nature
We talk about our own redemption and sometimes even the redemption of the earth or of the times or of art, but rarely do we think about the redemption of our sin natures themselves.
All things work together
Even things that are perfectly awful in and of themselves can be worked together into something more beautiful than before. Exhibit A: our sin nature. A terrible thing used to bring about the beautiful story of redemption.
Worth it.
Now, I’m not saying that, if we could do it over again we should still sin and fall. Bad idea. The point is that, when we can be so consumed in the beauty of Christ and his redemptive work that we view it as fortunate, or at least worth it.
tl;dr
The Fall of Man was felix, fortunate, because of the surpassing beauty of the redemption that God is now working in us.
