many years to come. we spoke to the senior pastor here just a little while ago. >> it is awfully difficult to memorialize because a memorial would be life lock for all of us, for the next four, five generations. because a person of his character, a person of his statute and commitment -- stature, will have a clear record of what he's done and i think his life will be much larger and much more impactful, in ten, 15, 15, 20, 25, 30 years now as it has been in the last ten, 15 years. >> they tell me that the night nelson mandela was released from prison in south africa they prayed here at the church all night long and when they got the news that he was released the whole place broke out into cheers. >> in many ways it's like his home church in los angeles.
