I have personally witness destruction of congregations from this movement. Not to mention that I was summarily dismissed from my local church because I refused to drink the koolaid.
I highly recommend James Sundquist’s book, “Who’s Driving The Purpose Driven Church?” to anyone who has not read it yet.
