Caution. This is maybe an AI generated sermon in Billy Graham's voice. There is a demonic movement afloat creating fake sermons from deceased men of God. I don't trust any sermon on YouTube anymore unless it's from an official channel (like BGEA). Maybe this one is real, but I know I've found fakes. Stay safe.

Totally.
I tend to look at the mouth and chin if it is a video. You can almost always tell if it is AI / deep fake based upon audio sync and coloration of the mouth and chin.
Audio alone is harder but cadence of phrases and specific words is the key to discerning there.
