According to Adherents.com, there are 6.6 billion people in the world today. Among these are 1.5 billion Muslims, 1.1 billion nonreligious people, 900 million Hindus, nearly 400 million Buddhists, 7 million Baha’is, and millions of adherents to countless other faiths. The Web site also says there are 2.1 billion “Christians,” a broad category that includes Catholics and Protestants, Mormons and Jehovah’s Witnesses, and so-called “nominal” Christians.
If the exclusive claims of Jesus are true, and even if everyone who claims to be a Christian really is, then 4.5 billion people still stand outside the kingdom of heaven. By all appearances, these people are sincere. They want to know the truth, and many believe they have found it. How can 4.5 billion people be wrong? Every Christian can answer this question by understanding the Biblical descriptions of those who do not know Christ.
