While preaching about forgiving ones enemies, the preacher asked for a show of hands of those who were willing to forgive their enemies. About half of the congregation raised their hands. The minister continued his lection and again asked for a show of hands. This time, 80 percent of his congregation raised their hands. Not giving up, the minister continued for fifteen more minutes. When he again asked for a show of hands, all members—except one—raised their hands."Mr. Jones,” asked the minster, “are you not willing to forgive your enemies?”"I don't have any.”Mr. Jones, that is very unusual. I know you are 86-years-old. Would you please come down to the front and explain to all of us how you have lived so long without making a single enemy in the world?”Mr. Jones teetered to the front and briefly explained, “Its easy. Ive outlived every one of them.”
