evidence: I don't quite know how misattributions like this one start, but I know how they continue. I read this quote, wrongly attributed to Nelson Mandela, in "Messy Spirituality" by Mike Yaconelli. I was really moved. Especially because I thought Nelson Mandela had said it. It's exciting to think that we all possess great power for good, and if Nelson Mandela, a man who fought some of the worst injustice, said that we are powerful beyond measure then it must be true. [...] That said, I doubt that, even with Nelson Mandela's name on it, this quote would've gained much mileage if it didn't genuinely resonate with people. It doesn't deserve to be discounted just because it wasn't said by Nelson Mandela.
