Billy Graham will no longer work with the president.

Billy Graham's work as a pastor to presidents is coming to an end, but he is praying for Barack Obama as the next U.S. leader begins his work, Graham's son said Friday on the ailing evangelist's 90th birthday. Franklin Graham said in an interview that his father's mind remains sharp even as his body continues to fail. But the preacher who has counseled every president beginning with Eisenhower is not in line to mentor Obama.

Billy Graham the man is frail, the legacy strong, "My father feels like his time and day for that is over," Franklin Graham said. "But he would certainly like to meet (Obama) and pray with him."

Graham's views of the world are still respected in White House circles. Republican presidential candidate John McCain visited Graham at his mountainside home during the campaign, and Obama tried to meet Graham but wasn't able to do so because of the preacher's poor health.

Though never partisan in his preaching, Billy Graham is a registered Democrat. His son expressed concern about Obama's views on abortion and gay marriage — an issue Franklin Graham raised in a meeting with the Illinois senator — saying that he and is father are conservatives who believe the Bible speaks clearly on those issues.

"President-elect Obama heard our position," Franklin Graham said. "And I told him that this was very difficult for us and hard for us. It's a moral issue that we just can't back down on."
"But he's our president-elect, and those positions that he holds that are contrary to Biblical teaching, I hope that God will change his heart," said Graham, who now heads the Charlotte-based Billy Graham Evangelistic Association.

Obama favors abortion rights, and does not support a constitutional amendment to ban gay marrage. He supports civil unions and believes states should decide their own laws about marriage.

About 160 of Graham's close family and friends celebrated his birthday with an intimate gathering Friday at his home in Montreat, featuring fried chicken, barbecue and sweet tea. His ministry had received some 100,000 greetings — including a video from President George W. Bush — from people who told stories about how he changed their lives. Graham's son said they would be bound so that someone could read a few dozen letters to him each day.

Encouragement is partly what Graham needs. He still struggles with the loss of his wife, Ruth, who died last year, and notes his father has more friends in heaven than on earth.

An avid consumer of news, Billy Graham still listens to television — he has macular degeneration and has can't read more than the headlines of a newspaper — and follows the events of the day. He spends much of his day napping and resting, and Franklin visits on Sundays to try and coax him to make the 100-yard walk to the barn next to the mountainside home in Montreat.

Graham's health is fragile. He was hospitalized overnight last month after falling over his dog while trying to pet it. He had elective surgery earlier this year to update a shunt that controls excess fluid on his brain. The shunt was first installed in 2000 and drains fluid from through a small tube, relieving excess pressure that can cause symptoms similar to Parkinson's disease.
Graham was hospitalized last year for nearly two weeks after experiencing intestinal bleeding, and he has also had prostate cancer. But Graham has still outlived doctors' expectations and some of the doctors themselves.
