Your Word is a lamp
for my feet
and a light on my path
(Ps. 119:105)

Now is the time of times to read and study Revelation using Dr. Constable's Notes on Revelation!  Learn "what will happen soon" in God's prophetic plan, and receive God's promised "blessing" for those who read and study this neglected prophecy, the last book of the Bible.
Learn about Jesus' comforting promise:
"I am coming soon!"


The sound [of their message] has gone out to all the earth
(Rom. 10:18)

Dr. Constable's Expository Notes in iSilo (.pdb format), as of January 2016, has been discontinued as a Sonic Light product.

For several years, an online .HTML format of the Notes has been available to anyone with internet access. Since this format works on both desktop PCs and handheld devices, there is no longer much demand for the iSilo format. This .HTML format utilizes Reftagger, an online Scripture reference system, and is accessed in the second set of OT/NT table-grids (click "Study Notes" tab above) of the Notes. It is recommended for users of iPad and advanced handheld devices. The .html-formatted files can also be read on older devices like the iPod touch, but with limited functionality.
