What one thing would disprove Christianity to you?

[Undeceived]

No, really. I want to know how the scientific method tests nonmaterial entities. Could you offer an explanation?

By testing their effect on material things. D'uh.

Then they would no longer be nonmaterial. If some "miracle" force healed people every time you did a certain procedure, we would call that force natural. The scientific method measures repeatable phenomena. If an event is repeatable, it must be natural.

I believe I answered this above, but to reiterate: We know the feelings come from God because they are not natural to the human psyche-- love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness and self-control. We don’t create them, the Spirit of God living within us does.

Except, we do know that they are natural to human psyche because we have a pretty good idea regarding their sources withing the human mind and we have the ability to artificially manipulate them to some extent. If the source was anything external , then that would not be possible.

The source is internal, either by God living in us or by our being made in the image of God. And we gain the fruits as we age. Does a person become more natural as they age, or less natural?
