I am convinced preachers try to teach from the “original” Greek or Hebrew in order to appear more scholarly. Does one or two semesters of a language make them more qualified than the God-ordained translators of the KJV, King James Version Holy Bible? Of course not.
Keep in mind their “original” Greek or Hebrew came from a modern translator in this century.
The work, God’s work in translation is already completed in the KJV. It was authorized by King James of England, who was appointed by God both to the Kingship and to the work.
So keep in mind, if there is a difference in meaning, in most cases it’s not you arguing with the original, its the preacher.
