Rodney Lensch was a significant leader during the Charismatic Renewal. Personally, I have been significantly influenced over the years by his clear and theologically accurate teachings. His ministry is called Rod & Staff Ministies and he continues to speak prophetically to the church via a quarterly newsletter called Rod & Staff. I just read this fall's issue and would like to share a PDF copy of it with you. (Rodney specifically states in each newsletter that it is okay to copy and share it.) I have been quite dismayed at the state the church is in these days and I sorely needed the encouragement Rodney speaks in this fall's issue.

I hope it encourages you as much as it did me.
