J. Gresham Machen delivered these addresses on the radio, which means they were written to be understood on first hearing by people with no theological training. The subject is the deity of the Savior, and the achievement is that nothing is conceded in the simplifying.

Timothy Keller writes that he has read and profited from these talks for decades and cannot recommend them enough; David Powlison that Machen's lucid exposition makes Jesus come forth as fresh as blue sky after days of dismal gray; Sinclair Ferguson that these pages constitute treasure hidden far too long; and John Frame that Machen's writing is always crisp and clear, without any compromise of cogent argument.
