Is Christianity making a comeback in America and the Western world?

In his book, The Surprising Rebirth of Belief in God, former UK broadcaster Justin Brierley offers a bold proposition: That the "withdrawing Sea of Faith is beginning to reach its farthest limit and that we may yet see the tide of faith come rushing back in again within our lifetimes.” Brierley argues that the first two decades of the 21st century represent the low tide of Christian belief in the West, a period that coincides with the rise and triumph of the New Atheism in popular culture. But recently things have begun to change. The New Atheism has suddenly become old and the intellectual climate in the Anglo-American world is shifting. Brierley's bold proposition may have just received some empirical support from the findings of the Religious Landscape Study conducted by the Pew Research Center and released in February of this year (2025). The study shows that the decline of Christianity in U.S. has stabilized over the last 4 or 5 years and may have reached something of a plateau. Is this a sign of a rebirth of Christianity in the Western World? If Brierely's own experience and assessment is on target, it just may be.
