What happens when Christian believers take the Word of God literally and begin to apply it where they spend sixty to seventy percent of their waking hours? What happens when they use their spiritual authority in their work lives, reflecting their spiritual value system in their area of influence? What happens when Christians move in a spiritual dimension in their work lives as few have endeavored to do before now?

What happens is that lives, workplaces, cities and nations begin to be transformed by the power of Jesus Christ. His prayer in Matthew, which says “Thy kingdom come, Thy will be done on earth as it is in heaven,” becomes a reality in the here and now.

Os Hillman is one of the leading authorities on faith at work today. The 9 To 5 Window: How Faith Can Transform The Workplace, provides an in-depth look at this new move of God and how Christians can practically implement their faith with their work life. Topics include facts on the current movement, how to bring the presence of God into your workplace, developing an intercessory prayer team at work, transforming your workplace, city, and nation for Christ, and much more. Hillman combines his ten years of experience working in the faith at work movement with 20 years as an advertising executive.

Bonus Feature: Includes a Bible study guide at the end of the book, ideal for small groups!

2 reviews for The 9 to 5 Window, by Os Hillman

  1. Pathmanathan Asokan

    I enjoy reading the book. It was very encouraging for me.

  2. Armand Dauplaise

    Chapter 9 was so inspiring that in late 2012 we formed a prayer team of 17 women who pray specifically as we request. Their intercessory prayer has helped guide us through 47 months of R&D with a patent pending product that is going to market later in 2016. I recently gave a copy of the book to a businessman friend.
