Why are J. C. Ryle's works so popular after over a century? Firstly, he expounded timeless Biblical truths using scripture, and secondly, he employed simple, concise, direct language. In "Knots Untied" Ryle explains what he means by "Evangelical" and presents and justifies the evangelical understanding of salvation, private judgement, baptism, regeneration, the Lord's supper, the real presence, the church, priests, confession, worship, the Sabbath, fallibility of ministers, idolatry, and other points. This classic is an excellent start for one wishing to understand or critique the evangelical position.
