Albert Llewellyn Hock became a pastor 67 years ago.
"I felt this was the best use I could make of my life here on earth," said Hock.
He was a pastor in St. Paul, Minn., for 39 years before moving back home to Strawberry Point.
He technically retired 30 years ago, he says.
Each Saturday morning, he has a Bible study group for residents at the Strawberry Point Lutheran Home.
"It's enjoyable," said Marilyn Brown.
Brown lives at the Strawberry Point Lutheran Home and has attended Hock's Bible studies for the last seven years.
"He's everybody's friend, and we miss him when he doesn't come," said Brown.
Besides Bible study, Hock also leads a worship service each Saturday night at the chapel in the Gernand Retirement Center in Strawberry Point.
"Also, every evening at 6, I have a 15-minute devotion at the retirement center where I live," said Hock.
On Sundays, he also serves as an interim pastor at vacant congregations across eastern Iowa.
"I love to write and preach sermons," said Hock.
Hock turns 95 in August. That makes him the oldest pastor in the North American Lutheran Synod.
Throughout his nearly seven decades as a pastor, Hock said he tries not to commit a pastor's greatest sin, which is to bore people.
"So I try to write sermons stimulating to the imagination," he said.
He said getting diagnosed with Crohn's Disease in January has slowed him down a bit, but not enough to keep him from doing what he loves.
Hock plans to keep giving sermons as long as possible.
