In Paul's letter to the Corinthians, he speaks about all of the faults and issues he has with the way they are dealing with faith. Most importantly, he is most concerned about the way they have watered down the gospel he has preached to them. Paul wants to hand on the good news of what we have received. It's so inconceivable, that we need to be reminded of it every time we gather because it's almost too good to be true. It is an eternal hope. What you believe matters.
