In a survey by the International Bible Society — indicated that 83% of all Christians make their commitment to Jesus between the ages of 4 and 14, that is, when they are children or early youth. The Barna Research Group surveys demonstrate that American children ages 5 to 13 have a 32% probability of accepting Christ, but youth or teens aged 14 to 18 have only a 4% probability of doing so. Adults age 19 and over have just a 6% probability of becoming Christians.
Because the 4-14 age period slice of the pie is so large, many have started referring to the “4-14 Window.” Many people serving as career cross-cultural missionaries have testified that they first felt God calling them to missionary service during that 4-14 age period.
It’s a fair question. How old were you when you accepted Jesus?
