This is perhaps the worst exegesis of the Bible that I have ever heard. Sure, I’m sure there is worse, but for a “pastor” to be “preaching” this in a “church”, this is almost unbelievable. I’ll leave it at that and let you have a watch. It’s less than 5 minutes.
For the record, so as to avoid any splash or mess that I or my wife may have to clean, I do sit down when taking a leak, and I am fully confident that such an act does absolutely nothing to my manliness or God’s view of me. God sees me through Jesus, not through my urination standards.
