It is sweet to do nothing, but only if if the inactivity comes like the caesura in a line of poetry or the punctuation in a sentence of prose or the rest in a piece of music. Inactivity extended stultifies. At least this is true here below. Genesis 3:19 may be read as 'sentencing' us to activity. Enduring contemplative repose comes later.
Or does the 'sentence' end with a 'full stop'?
