I think your blind in some ways but on the right path in others. You found what works for you, doesn't mean it will work for others.
That sermon could be 1000mins long it's still his opinion on what he concluded of his study.
Porn is bad when overdosed just like drinking bleach and crack and gambling and heroin and helium. Get my point....
1st off a church has its good leaders and bad leaders, just like governments, which are quit frankly similar.
Church was formed by a group of people, whom had the same belief. Soon other forms of that 1st group broke off with their own beliefs.
Churches found out that they had sway over the mass of people and pushed this belief. Most wars were religious based in the old days. Till "land, slaves, gold(many forms), influence and even freedom of prosecution" took over.
Weak minded people follow...strong minded lead.( not always true...or straightforward)
I've been to many churches, ccd, baptized and confirmation. I've come to the conclusion that I believe in myself 1st and foremost.
I do watch porn, my wife and we have a healthy relationship.
I conclude that this sermon is his opinion based not on fact but assumption to the data he sees. Fact is something that is 100%. I don't see the same thing.
