Hello,
I’m Dennis Tuuri
I’ve been a pastor and Bible teacher for over forty years. My passion is helping Christians think biblically about all of life — work, rest, family, community, and our responsibilities as citizens.
This site is a home for my teaching: sermons spanning decades of expository preaching, a book on the Christian Sabbath, and voter guides for faithful civic engagement.
Thanks for visiting. I hope these resources are a blessing to you.
