As a boy in Sunday School, Michael Roland was puzzled when the Sunday School teacher read the fourth commandment to the class. Why did God say, "The seventh day is the Sabbath of the Lord thy God"? By the calendar it was plain to see that the seventh day was Saturday, yet Sunday seemed to be the day set aside as Sabbath. Neither his teacher nor his mother could explain this to him.

When Roland grew up and joined the navy, he learned about the true Sabbath and the reason for keeping it holy. But how does one keep the Sabbath in the navy, especially on a submarine?

You won't want to put down this book until you've finished the story of how Petty Officer Roland served both his God and his country, even though many times insurmountable difficulties seemed to arise.

This is a story of courage, perseverance, and witnessing in a modern-day setting.
