At one time, Methodist Preachers had a simple message: Get Saved or burn in Hell for eternity. So, a young boy like me in the 50s did not need to speak Greek to understand that message.
Saved was not that complicated according to my Reverend Uncle. It meant you came down the aisle on Sunday to make a profession of faith or agree with what he said and later that evening get sprinkled with water. (Baptist must go under water).
The difficult part is living by Christian principles.
