Romans is the chief book of the New Testament, and is truly the purest gospel. It is worthy that every Christian should occupy himself with it every day, as his daily bread of the soul. We can never read it or ponder over it too much; for the more we deal with it, the more precious it becomes and the better it tastes. In this epistle we thus find things that a Christian ought to know, namely, what is law, gospel, sin, punishment, grace, faith, righteousness, Christ, God, good works, love, hope, and the cross. We also learn how to conduct ourselves toward everyone, be he righteous or sinner, strong or weak, friend or foe. This is all supported with Scripture and proved by Paul’s own example and that of the prophets. It appears that Paul wanted in this one epistle to sum up briefly the whole Christian and evangelical doctrine, and to prepare an introduction to the entire Old Testament. For, without doubt, whoever has this epistle well in his heart, has with him the light and power of the Old Testament. Therefore let every Christian be familiar with it and exercise himself in it continually.
