Reaching people who have never heard is not the same as leaving a tract in a bathroom. Justin Long suggests that perhaps the question we should be asking people is “how may I pray for you?” to start something more than a confrontation… He writes:
That 86% of Muslims, Hindus and Buddhists do not personally know a Christian is thus a big deal. Those who have access to the Gospel–those who have heard the Gospel–are mostly people who know Christians (and most of those are due to Christians in their family).
Getting Christians into the daily lives of Muslims, Hindus and Buddhists requires intentional action that is far more challenging than simply purchasing radio broadcast hours, donating to the distribution of Bibles, or leaving tracts in bathrooms.
