This is one of my favorite study tools!  It gives me the ability to see how other passages relate to the verse under study.  Access to those references is very easy.  Click the button on the left to begin.

When you open the site, you will have an area to enter the key verse.  The default translation is the King James  Version
The words used to generate the cross-reference are highlighted in red.

Below that, the verse results are displayed listed by the highlighted words.    You can click the verses one by one in the left column.  Or reveal all the cross reference with a single click.  Easy-peasy.
