"When I get to heaven I shall see three wonders there: the first wonder will be to see many people there whom I did not expect would be there; the second wonder will be to miss many people whom I did expect would be there; and the third and greatest wonder will be to see myself there. - John Newton, author of Amazing Grace, as quoted in Spurgeon's Sermon Notes
