Sister Burton's instructions on how to serve---to observe first---is, I think, vital if we are to do Christ's work. Take home and visiting teaching.
Remember Sister Beck's story of the visiting teachers who showed up to interrupt their teachee's day with a lesson while a husband lay immobilized and toddlers threw cereal and dishes remained unwashed? We can't plan out service years in advance and have it be sufficient. We need to observe and then serve.
We are all called to serve. But are we paying attention to see where and when and how?
So wake up and do something more.
