Online Commentaries
The Westminster Confession states, “All things in Scripture are not alike plain in themselves, nor alike clear unto all: yet those things which are necessary to be known, believed, and observed for salvation, are so clearly propounded, and opened in some place of Scripture or other, that not only the learned, but the unlearned, in a due use of the ordinary means, may attain unto a sufficient understanding of them” (WCF 1.7). This means that there are portions of Scripture that are difficult to understand and interpret. Thankfully, God has gifted the church with teachers to assist the saints in understanding the Bible (Eph. 4:11-13). One way these teachers have done this is by writing commentaries on the books of the Bible. There are many helpful commentaries online that are in the public domain (i.e. free). StudyLight.org provides a large list of online commentaries; some are good, and some are not so good. We have selected some commentaries that, by and large, provide sound doctrine and exegesis. The Scriptures are infallible, but men are not; therefore, the reader should be a Berean and “examine the Scriptures daily” to see whether the things written by the commentators match what is written in the Scriptures.
