A pastor who publishes a book on sermons should believe all the words of Christ so therefore to me you are saying Dr. Martin Luther King was illogical.If a Christian is required to believe everything in the bible is true, then by that standard, it was an illogical decision. If a Christian is not required to believe everything in the bible is true, then it wasn't.
Do you claim that a Christian is required to believe everything in the bible is true?
