What is the significance of the number 120 being three sets of 40 in Scripture?
The number 120 is significant because it is three sets of 40. In Scripture, 40 is a time frame God has used over and over again. Thus 120 intensifies that pattern, and in the context it also marks the 120th Jubilee since Adam, showing how God's time frames fit together.
Les teaches that 120 is three sets of 40, and 40 in Scripture is always a time frame that God has used over and over again. He connects these numbers with the 120th Jubilee since Adam, which he places at the fall of the year 2000. In the same fall, he notes it would be the 70th Jubilee since Joshua led Israel into Canaan, and the 40th Jubilee from the time of the crucifixion. These figures, he says, show how completely God's time frames fit together. He also cautions against tying oneself to that date as the time of the Lord's return, noting that this refers to His second coming, not the rapture.
