Rev. Meg Barnhouse's sermon delivered on April 6, 2014. The Third Commandment forbids taking God's name in vain. So many people say "God bless you!" to the poor but do not help to change the situation. So many politicians say "God bless America" at the end of their speeches, but what do they mean by that? Might using God's name for ulterior motives be taking that name in vain?
