"Will it give you more time to pray?"

In his book Rediscovering Values, Jim Wallis recounts an interaction with an agnostic friend.  His friend was interested in the virtual religious experience available through contemporary technologies.  His friend asks this insightful question, "Will it give you more time to pray?"

Shouldn't we be asking ourselves that same question regarding all our "time saving" conveniences?  I'm not sure we'll like our answers.
