Puritanism is a wonderful antidote to the harmful and needless divisions which are caused by adding man-made rules to Scripture. Worldliness is an enemy. The cure is in the heart. A man can keep many rules, but be worldly still and at the same time possess a deadly spirit of Pharisaic self-righteousness. Puritanism concentrates on the great issue of the state of a person’s soul. When a soul is truly joined to Christ every part of the person – his thoughts, words and actions – will be subject to the Word of God. While he makes rules for his own life, he will avoid making them for others.
