Covetousness

Lk 12:22-23
And he said to his disciples,"Therefore I tell you, do not be anxious about your life, what you will eat, nor about your body, what you will put on. for life is more than food, and the body more than clothing."
Lk 12:34
For where your treasure is, there will your heart be also.

For me, and I think for some others in the upper realm of our culture, it's not so much about clothing, food or material per se, but a general sense of security on whatever we choose to believe in. Be it art, love, democracy, change, humanity, there's a point where beliefs as such tip and overturn. Anxiety is a sign of sin, of covetousness, a pernicious effort to revolt against God. It stands in our way in truly believing in the Gospel, the life beyond what we perceive.
