Hugh Martin (1822-85) combined a brilliant analytical and mathematical mind with a child-like heart which rested in Christ and his atoning work, as revealed in the Scriptures. Most of the sermons in this book were transcribed from Martin's notes by the late Principal James Mackintosh of the Free Church College. The title is taken from Martin's remark: 'The Scriptures in explaining the scheme of redemption make frequent use of expressions of this general form: "Christ for us" . . . Jesus was by the Father appointed . . . our Surety, our Representative. The scheme of redemption is founded on a marvellous exchange of places between Christ and his people, he taking theirs, they being translated into his . . . He became Christ for them.'
