4/14 Window Global Initiative Booklet

At the end of the last century I wrote a pamphlet entitled The 10/40 Window: Getting to the
Core of the Core. In the first years of this new century, I am urging a new missional focus: The 4/14 Window. Although in a different sense, it too can be called “the core of the core.” The 10/40 Window referenced a geographic frame; the 4/14 Window describes a demographic frame—a life season comprising the ten years between the ages of 4 and 14.
