If there is a practical demonstration of the saying "Behind every great man there is always a great woman," it is represented by the union of Giuseppe Di Biagio and his wife Rosemarie. The renowned preacher and evangelist, one of the foremost scholars of the biblical subject of "The Return of Jesus" or "Eschatological Preaching," indeed had by his side for over forty years a woman who lived the role of wife, supporter of her husband, and member of a family whose foundation is Jesus Christ, in the deepest Christian sense.

In this short writing, A Life in Service of God, Rosemarie Di Biagio wished to recall, with all the tenderness of a life partner, some significant moments of her human and Christian experience with her husband, a few years after Giuseppe's death in March 2010. A portrait that confirms Giuseppe Di Biagio's figure as one of the most important for the Italian evangelical movement, but above all, a true man of God, of great faith and determination. A man who, together with his wife, always sought and found God's guidance for his life and for his Christian testimony.
