I had the opportunity to preach last Sunday at Antioch. Aaron Wells and I delivered a "nunchuck sermon," the two of us separated by a worship song; it was the wrap-up of the summer preaching series in 1st Peter. You can listen to or watch the sermon here.
My portion was apologetic, and I sought to show the reasonableness both of believing the promise contained in 1 Peter 5:10 and of accepting the existence of the devil (verse 8). Regarding the latter, I argued that the question of the existence of demons is part and parcel of the larger question of whether materialism (the metaphysical view of many modern scientists) or biblical dualism is the correct understanding of the world in which we live.
I promised during the sermon, though, to blog about scientific evidence specifically for the existence of demons. So look for that in the next post (or two).
