Billy Graham will turn 91 years old this Saturday.

He plans to celebrate his birthday at home with family in Montreat, North Carolina.

The ministry says Graham's sight and hearing have declined. But he uses a walker and "remains in good overall health with a strong heart and clear mind."

Graham says he misses his wife, Ruth, who died in 2007, and he looks forward to being reunited with her in heaven.

The evangelist says he's been blessed in his senior years to see his children, grandchildren and great-grandchildren develop their own ministries.
