There's a big difference between rest and laziness. It's important, especially in recovery, to sometimes step away from the busy schedule and rest. No TV, no phone, and nothing on the calendar - just you and God.
In my experience, God has shown up in my life at some pretty random times. There isn't a set time in my day where I can expect to have a spiritual experience. Why then, should I live my life always having to be at a certain place at a certain time?
Staying busy can be good, but only if you're busy with the right things. Pray, love others, and rest :)
