The Game with Minutes

Frank Charles Laubach was an Evangelical Christian missionary and mystic known as "The Apostle to the Illiterates." One of his most widely influential devotional works was a pamphlet entitled "The Game with Minutes." In it, Laubach urged Christians to attempt keeping God in mind for at least one second of every minute of the day. In this way Christians can attempt the attitude of constant prayer spoken of in the Epistle to the Colossians.
The pamphlet extolled the virtues of a life lived with unceasing focus on God.
