Servant versus slave: opening the question

• Is there a biblical distinction between being a servant and being a slave?
• Does God call Christians to be weak?

A host frames the night's first big topic: whether there is a biblical distinction between being a servant and being a slave, and whether God calls believers to weakness. The hosts agree service gets a bad rap because worldly servanthood invites being used, land on willingness as the difference -- a servant chooses, a slave is placed -- and trade stories about tipping servers and sharing late-night meals with a truck-stop night crew.
