From Dietrich Bonhoeffer's book Meditations on the Cross, the chapter entitled "Worldliness".
Without or against the proclamation of the cross of Christ, there is no realization that the world is god-less, without God, and has been left to itself by God. Rather, what is worldly will always try to satisfy its unquenchable longing for deification.What in my life tries to deify itself, because it stands alongside the cross of Christ instead of below it? Am I idolizing (i.e. turning into an idol) anything or anyone?
(You didn't miss the Day 6 quote. I didn't post one. The reading didn't lend itself to excerpt.)
