I think that all too often, pastors are given free reign and can easily be caught up in having the 'power' of leading a church. Not that a pastor should not have our respect, but they are sinners like the rest of us, and need to be held accountable. It is not uncommon to read the news and see that another pastor has fallen into deep sin, whether it be sexual or not. I feel like there are always warning signs before these grave sins are committed.
I believe it is our responsibility as church members to pray for our pastors and for there to be Biblical accountability set up within a church's structure.
They also mention a readers comment that is definitely worth mentioning about seeing sexually explicit material:
"Have you viewed sexually explicit material?" is a much better question than "Have you looked at pornography?" because I can click on sexually provocative news stories or click on links that I know will have scantily-clad chicas on them and still pat myself on the back at the end of the week, saying, "I didn't look at pornography!" Uh-huh. The deceitfulness of sin at work.
