I was just thinking the other day, about what Jesus said concerning the end of the system of things. He said that, "No one knows the day or the hour...but only the Father."
There are two units of measurement - day and hour
Now consider other scriptures in the Bible which include one or both of these units:
Genesis 1:5 "God called the light Day, and the darkness he called Night. And there was evening and there was morning, one day. "
Genesis 2:16,17 And the LORD God commanded the man, saying, "You may freely eat of every tree of the garden; but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you shall die."
2 Peter 3:8 But do not ignore this one fact, beloved, that with the Lord one day is as a thousand years, and a thousand years as one day.
Revelation 7:12 - And the ten horns that you saw are ten kings who have not yet received royal power, but they are to receive authority as kings for one hour, together with the beast.
Notice that these highlighted units of time are not to be taken literally.
When Jehovah created the earth, it was thousands of years, not days. Adam died in the day he ate of the fruit, but not the literal 24 hour day. He died at 930 years of age. The UN will rule for a short period of time, not a literal hour of 60 minutes.
In almost all cases of "day" and "hour", they symbolize not their literal unit of measurement, but a different unit of measurement. One day can be a thousand years to God, one hour can be a century.
What is the point of this?
Conside this verse again...
"No one knows the day or the hour...but only the Father."
How do we not know that the day is any period of a thousand years, and the hour is a century or shorter period of time, within that thousand year day?
Of course, the Witnesses say that Jehovah has a set day, and they're partly right. But maybe the scripture is talking about a set day of a thousand years, rather than a Monday, a Tuesday or a Thursday.
Something to consider.
