This site provides a great number of study tools including Arcing and Bracketing. It also provides the NET translation as one of the core sources; this is a favorite of mine to use since it includes “Translator Notes” (information provided by the translators regarding a particular verse and their issues in doing the translation).

The main source for the sermons from John Piper.

A mobile App is available.

A specific set of sermons where Dr. Piper teaches how to study Scripture. As part of this, he uses a special visual tool that allows him to annotate in real time as he goes - a really great way for him to show how he processes through understanding a passage.

The home of Reformation Magazine; editor-in-chief is Michael Horton. Loosely affiliated with Westminster Seminary in San Diego, CA.

The main source for the sermons from John MacArthur.

A mobile App is available.

A great solution for Churches to publish sermons, events, music, giving, and more. Metro Calvary has been using this solution for many years (and I have been helping to manage it for several as well). An example of how sermons can be shown and categorized can be seen here.
