Jailer
(of Philippi), Acts 16:23. The conversion of the Roman jailer, a
man belonging to a class "insensible as a rule and hardened by
habit, and also disposed to despise the Jews, who were the
bearers of the message of the gospel," is one of those cases
which illustrate its universality and power.
