His conviction is that 1 Corinthians is uniquely a tract for our times. His aim is that churches will recognise the problems and tensions inherent in being God's people in the increasingly urban world today, and not be ignorant of the true spirituality that is the work of the Holy Spirit. He wishes for each of them as a body to grow to express the total lordship of Christ.

For Paul, he points out, Corinth as a strategic test case: if the gospel of Christ could change lives there, it could do so anywhere. He saw in the Corinthian believers the rich resources for Christian ministry and mission that are present in every local church.
