Edmund Clowney, author of Preaching and Biblical Theology and Called to the Ministry, has also written a Biblical Theology of Prayer that is available free, via a downloadable PDF.
Clowney’s treatment of a call to the ministry (a term I don’t really like) is one of the best I have read. Regarding a call to ministry, Clowney greatly values testing one’s gifts in the context of the local church and having those gifts confirmed through such service.
Clowney’s work on preaching is an excellent, Christ-centered treatment of this critical and central responsibility of a pastor. I am sure that Clowney’s work on prayer is likewise well worth digesting.
