I have been thinking about the reactions I have received from people after explaining grace to them, and came to the conclusion that I would be more satisfied with someone who got angry at the message rather than someone who just sits there, giving polite nods and smiling at me, all the while disagreeing with me.
At the very least let me know you understood what I have spoken to you. Please, show some sign of comprehension! I could say I somewhat understand what the Lord felt when he pleaded with a Church, "Would I that you were hot or cold! But you are lukewarm!"
If you reject the message, then reject it with passion! Perhaps then you would be zealous enough to read the Scriptures and find out if these things are indeed so. But if you sit there, passive and indifferent, then what hope is there of you ever even caring to understand?
The Gospel is not something to be indifferent about. You are either for it or against it.
