"Holiness is the habit of being of one mind with God."? In this classic collection of twenty soul-nourishing essays, as relevant and helpful today as when first published in 1877, Ryle endeavours, "by God's help, to examine what true holiness is, and the reason why it is so needful."? The first part of the book examines the doctrine of holiness, from sin and sanctification, to holiness, our fight for personal holiness, what it costs to be a true Christian, growth in grace and how a lack of holiness often leads to lack of assurance. In the second part, Ryle gives warmly drawn instruction from scriptural characters. Moses, Lot, Lot's wife, the dying thief and the Lord himself, teach us valuable lessons about holiness or the sad effects of its lack. Ryle concludes with a collection of practical and devotional essays, ending with the exhortation 'Let us live on Christ. Let us live in Christ. Let us live with Christ. Let us live to Christ. So doing, we shall prove that we fully realise that "Christ is all."?
