Pretty much every speaker I've heard in church states only what they know to be true about the church.  I don't think I've ever heard anyone admit to not knowing something.  For me, I think it would be beneficial to hear if other members had shortcomings when it comes to their testimony of the church.  I would like to know I could relate to more people out there like me who have things to work on. Do you think the following examples would be appropriate to say from behind the pulpit?
