Irreligiosa sollicitudo pro Deo - this wonderful expression means "a blasphemous anxiety to do God's work for him."
This is the anxiety that causes us to be frantic and panicked. We are frazzled and hassled because the work is not done. And for some reason we are not able to get it done. This anxiety does not allow us to rest or to be still before God because their is something else that needs to be done.
Mark Buchanan states that we should still rest. Not because the work is finished but because God is God. Our rest states that we cannot do the work. It declares that the work is not really ours anyways. It is God's work. And he invites us to partner with him in doing it but he also tells us to rest. The world is not resting on our shoulders. God is able to do more with and threw us if we spend times being still before him.
This is not an excuse to be lazy. It is a call to allow God to be God. And for us to stop trying to do his work.
