Why Do Preachers Commit Adultery ???

Why do we become unglued when we hear of a Pastor/Preacher having been caught in or confessing adultery? Why do we see them so different from all the other men in the world? The last time I checked, my flesh didn't get saved when I trusted in how Jesus died, was buried and rose on the third day. Look at Apostle Paul's writings in his Epistles. Sure seems like he understood what kind of sinner he was AFTER his salvation. How can you know if someone is saved? What is your "measuring stick"? How should we talk with someone who is really struggling with the sin in their lives? What do we do? What do we say? Reminder, there is no excuse for sin.
