“[Romans] is a light and a way unto the whole Scripture.   I think it meet (important) that every Christian man know it by rote…as the daily bread of the soul.   No man can read it too often, or study it too well; for the more it is studied, the easier it is; the more it is chewed, the pleasanter it is; and the more grandly it is searched, the more precious things are found in it, so great the treasure of spiritual things lie hid within.”  - William Tyndale (1494-1536)
