About Sonic Light

Thank you for visiting Sonic Light.

Sonic Light began in 1996 when a church member at Plano Bible Chapel realized that there was an enormous treasure of Bible study lessons on audio tapes that were not widely used, nor were they easily accessible in series form. These tapes were converted to a computer format where they could be easily accessed by others on the internet.

Dr. Thomas L. Constable

Over the years, hundreds of Bible lessons, most of them by Dr. Thomas L. Constable, were converted to the digital MP3 format; many of them are now available for free listening at this website, or they can be purchased on CDs (also known as Study CDs.) In 1999, Dr. Thomas Constable began publishing his expository (Bible study) notes on Sonic Light for his students at Dallas Theological Seminary. These excellent notes are not only used by Dr. Constable's students, but they also receive thousands of visits per day from a worldwide audience. Beginning in 2002, these notes became available for PDA handheld platforms and have been very popular.

In June 2004 a graduate of Moody Bible Institute, Mark Farstad, became the webmaster of Sonic Light. He grew up in Ecuador, South America, where his parents served as missionaries for over 20 years. Mark trusted in Christ at a young age in Arajuno, Ecuador. While growing up in Ecuador, Mark attended The Alliance Academy in Quito, a 12-grade school established in the early 1900s for missionaries' children. After high school graduation in 1973, he attended Moody Bible Institute in Chicago, from which he graduated in December 1977 as a foreign missions major. Shortly thereafter Mark started working with his uncle, Dr. Arthur Farstad, on various Bible translation and Bible commentary projects. Since the 1980s, he has continued doing this type of work.

Mark Farstad Sonic Light Webmaster

During the 1980s and 1990s, Mark worked as editorial assistant to Dr. Arthur Farstad, who was the chief New Testament editor of the NKJV Bible translation. He also worked on the Believers Bible Commentary written by the late William MacDonald. In the early 1990s, Mark and Dr. Art Farstad began work on a modern English translation that was first named Logos 21. A Bible organization named Absolutely Free sponsored Logos 21 in 1996. Much of this work was later adapted by Holman Publishers, which contracted with Dr. Farstad to make a new, optimal-equivalence Bible translation that became known as the Holman Christian Standard Bible. The first edition was completed in 2003.

In 2004, Sonic Light's original designer and first webmaster, who prefers to remain anonymous and is the same Plano church member mentioned above, offered to sell the website to Mark Farstad, who subsequently bought it and became the new webmaster.

Sonic Light is both a ministry and business, not financially supported by any corporation, church, or organization—a "self-supporting" endeavor. Since there is no organizational or regular support, the website depends largely on website visitors or Bible students who benefit from using Dr. Constable's audio Bible Studies or expository notes, and either purchase Sonic Light's products or give a financial gift.

Thank you for supporting Sonic Light. Please pray for this work, that it might bless many people; that God's Word will be used by this web site to teach and strengthen many believers in their faith; that people will grow in their knowledge of Christ through these Bible studies and Constable's Notes.
