Rev. Billy Graham says if he had it to do over again, he would steer clear of politics, according to Christianity Today.

Despite struggling with health issues, the 92-year old evangelist continues to council and advise world leaders. He has ministered personally to every president from Truman to the Bush family. He also recently met with President Obama.

"People in power have spiritual and personal needs like everyone else, and often they have no one to talk to," Graham said. "Looking back, I know sometimes I crossed the line, and wouldn't do that now."

The 92-year-old evangelist also told the magazine that he wished he had spent more time with his family, had studied more, and preached less. He warned of the temptations achievement can offer.

"Success is always dangerous, and we need to be alert and avoid becoming the victims of our own success," he said.

Though he does make occasional appearances, Graham now spends most of his days in Montreat, N.C., where he receives around-the-clock care.

His son Franklin Graham admits his father would like to preach again, but a date is not yet confirmed.
