Since anyone can remember, the Gods have protected your little village. At night they guard against evildoers; they bear away murderers and thieves and blasphemers, and purify their souls. Sometimes the evildoers don't survive the process; sometimes they come back shadows of what they were. At least they have been purified.
And did the Gods not descend from the mountain when the Northmen came? Did not Lord Samyaza himself cleave the Northman chieftain from shoulder to waist, and bathe in his blood? Did not Lady Berith beguile half the warband, take their evil souls, and transmute them within herself into pure flame? Glorious was that day, to see the power of the Gods made manifest.
Yet, this morning strangers come to the village. They call the Gods an evil name, and seek to recruit blasphemers and ne'er-do-wells to their cause. The strangers say they will venture up the mountain, break into the fortress of the Gods, and "destroy" them. (Destroy them? They are Gods; how can mortal man destroy them?)
What do you do? Slay the strangers? Bind them for judgement from the Gods? Do nothing, and wait for the Gods to smite them? Or perhaps give in to the blasphemous doubts in your own heart, and join them ...?
