This series of lessons deals with what is commonly called "The Gap."This term ("the Gap") refers to a gap of time between Genesis 1.1 and 1.2, a gap where one can easily "fit" (and explain) the fall of Lucifer and his angels.
A gap of time between verses of Scripture (or even between words of one verse) is not at all uncommon in the Bible. For example, in his book Principles of Biblical Hermeneutics, J. Edwin Hartill dedicates a chapter to what he calls “The Gap Principle” (gaps of time in Scripture). Hartill explains: “That the principle of divine revelation whereby God in the Jewish Scriptures ignores certain periods of time, leaping over centuries without comment” (from page 92 of the aforementioned book). This is exactly what we have between Genesis 1.1 and 1.2: God leaps over a key event in creation history without so much as a comment.
Hartill adds that between Revelation 12.5 and 12.6 there is a gap of 2,000 years that includes not only the Church Ages (after the ascension of Christ at the end of verse 5), but also the first three and a half years of the Tribulation Period. The woman (Israel) doesn't flee into the wilderness until after the mid-Tribulation “abomination of desolation” mentioned by Christ in Matthew 24.15. In Isaiah 9.6-7 there is a gap of 2,000 years (again, the time frame between the two advents of Christ; the Church Age) between the first phrase of verse 6—“For unto us a child is born, unto us a son is given...” (first coming)—and the remainder of the passage which speaks of the Lord reigning during the Millennium (secong coming).
There are gaps in the Scripture—periods of time that God simply passes over without comment. Frankly, as one reads and studies the Scripture, it seems like that is how God does things (using gaps, revealing things that were before hidden and not clearly understood). So, if there are gaps of time in other parts of Scripture and history, one cannot rule out the possiblity of a gap between Genesis 1.1 and 1.2. This study deals with just that span of time which become essential to understanding New Testament salvation.
