Try filling out the worksheet for this Age by looking up the scriptures before you see the answers below. You should be able to fill in all the entries except for the first three, and also calculate the total time-period:
Adding up the years of this Age gives a total of 2008 years. Although this is very close to 2 DAYS (2000 years), we have seen that the Jubilee Principle applied to the structure of time leads us to expect a total of 1960 years on the Redemption Chronology. This means that there must be 48 (2008-1960=48) unreckoned years.
When Adam sinned God immediately announced the Coming Messiah who would be a man, the Seed of the Woman: "I will put enmity between you (satan) and the woman, and between your seed and her Seed (the Messiah); He shall bruise your head, and you shall bruise His heel” (Genesis 3:15). The plan of Redemption would focus on this unique Man. Starting with Adam the Bible traces the human descent of Messiah through the godly seed-line leading up to Abraham and then we are told that the Messiah would be the Seed of Abraham. Therefore before the birth of the Messiah the Plan of Redemption centred on this godly seed-line, and God measured Redemption time through them.
Was there a time when the Plan of Redemption was suspended because of sin? Was there a disruption in this seed-line to Messiah. Yes, Abel was originally the righteous seed, but satan stirred up his brother Cain to murder him (Genesis 4). God had to replace Abel with another Seed: "And Adam knew his wife again, and she bore a son and named him Seth, “For God has appointed another seed for me instead of Abel, whom Cain killed” (Genesis 4:25). The time taken to acheive this represented a delay in the progress of the Plan of Redemption and so the time between Abel's death and Seth's birth was UNRECKONED TIME. This accounts for the 48 years unreckoned time.
Abel is a Type of Christ, the righteous seed, the Good Shepherd who offered up a pleasing sacrifice to God, yet was killed by his brothers, but whose blood still speaks.
Applying this typology, the best reconstruction of this time is as follows:
1. Abel is born at the first Jubilee at Tabernacles (after 48.5 years).
2. Abel was killed at Passover at age 33.5 years exactly like Christ.
3. Seth was born 48 years later.
This makes a total time of 48.5+33.5+48=130 years from Adam to Seth as given by Genesis 5:3. We can now fill in the first three entries in the chart (see below). Note: the figures in the chart are rounded.
