Walter Marshall was an English Presbyterian minister – a Puritan – best known today for this excellent work on sanctification. Born in 1628, he was forced to leave his parish in the infamous Great Ejection of 1662. However, he remained faithful to the call of God, shortly finding another congregation which he pastored until his death in 1680.
