You were blameless in your ways from the day you were created till wickedness was found in you. Through your widespread trade you were filled with violence, and you sinned. So I drove you in disgrace from the mount of God, and I expelled you, guardian cherub, from among the fiery stones. Your heart became proud on account of your beauty, and you corrupted your wisdom because of your splendor. So I threw you to the earth; I made a spectacle of you before kings. Ezekiel 28:15-17
When most Believers consider the fall of Satan, they almost unanimously believe that his fall must have occurred prior to the creation account of Genesis Chapter 1. This belief however, has given rise to many attempts to force theories onto the Scriptures such as the Gap Theory or Day/Age Theory in order to make them fit an artificial template.
However, what does the Bible say about the timing of the fall of Satan?
1. Everything was created in six days. (Exodus 20:11)
2. Satan was created. (Ezekiel 28:13, 14)
3. Satan was in Eden until he sinned. (Ezekiel 28:13-15)
4. Eden was made on day 6. (Genesis 2:8)
5. Since Angels were created to be “ministering spirits” for us (Hebrew 1:14 and Matthew 18:10) why would God create them millions of years before man?
6. Satan and the angels rejoiced when the foundations of the earth were laid. (Job 38:4-7)
7. The foundations were laid on day 3. (Genesis 1:9)
8. Everything was “very good” at the end of day 6. (Genesis 1:31) (Wouldn’t make sense to say so if the Devil was running around down here as a villain).
9. Adam was 130 when Seth was born. (Genesis 5:3)
10. Cain & Abel born an unknown number of years before Seth.
Therefore, according to the Bible, there are no theological or doctrinal grounds that prevent Satan from existing, unfallen, on earth, after the creation, for at least the first 100 years.
