Why would joining the perfect church spoil it, according to Les's story?
According to the story, joining the perfect church would spoil it because the person joining is not perfect. His presence would introduce the very imperfection that the perfect church lacked. The remark implies that an assembly of flawless believers cannot remain flawless once an imperfect individual becomes part of it.
Les had said that if anyone found the perfect church like the one in Acts chapter 2 and 3, he would join it. A listener replied, 'Don't you do it, Les, because that'd spoil it.' Les agrees this is true. The implication is that the perfect church is perfect precisely because imperfect people are not part of it; adding an imperfect person would introduce the flaw it lacked. The context contrasts the early church's unity and Spirit-filled boldness with the local churches his audience knew, showing that no earthly church today matches that perfection.
