Some reputable sociological research indicates that a surprising number of evangelical churchgoers are living out a version of the Christian life that's more informed by the values of the surrounding culture than by the discipleship teachings of Jesus and his apostles. Viewing the cause of this disturbing trend in the church to be a “discipleship deficit” that's exacerbated by a “pneumatological deficit,” Gary Tyra has written a book that addresses both. In this work, Tyra encourages evangelical Christians of all stripes to become more fully aware of the tremendous difference it makes when the Holy Spirit is experienced in ways that are real and existentially impactful, rather than merely theoretical, conceptual, and/or ritualistic. Intended to be read by church leaders as well as by students in Christian colleges and seminaries, the message here is that the cure for the ministry malady currently confronting us is the recovery of a robust, fully Trinitarian doctrine of the Spirit. A pneumatological realism, says Tyra, combined with an understanding of just how important a spiritual, moral, and missional faithfulness is to a genuine Christian discipleship, can revitalize the lives of individual Christians and churches, making it possible for them to reach their post-Christian peers for Christ!
