As you study the Marvelous Work and a Wonder you will come to realize that the term is virtually always synonymous with the term RESTORATION when used in the scriptures speaking about the events of the last days.
As Latter Day Saints we commonly refer to the 15 year ministry of the Prophet Joseph Smith as the time of restoration because this is the time period in which the church was restored to the earth..
Although the LDS restoration movement in the 1830's was a time of restoration for that reason, the term restoration really confuses many Latter Day Saints because the scriptures NEVER use the term "restoration" to refer to the time when the church was restored in 1830! The Book of Mormon the the D&C always use the term restoration to refer to the events of the last generation of time spoken of in Matt 24.
Do a key word search on the word restoration in the D&C and the B of M and you will be surprised at what you find!
Here is one of my favorite uses of the term restoration by the Prophet Joseph Smith
15 Q. What is to be understood by the two witnesses, in the eleventh chapter of Revelation?
A. They are two prophets that are to be raised up to the Jewish nation in the last days, at the time of the restoration, and to prophesy to the Jews after they are gathered and have built the city of Jerusalem in the land of their fathers.
As you can see from this question and answer period that Joseph conducted, the time of the restoration is the time when the two witnesses mentioned in the Book of Revelation are on the earth.... during the last generation... during the Marvelous Work!
In future posts I will discuss other scriptural uses of the word restoration that give additional clarity and proof that the final restoration of all things, which is synonymous with the Marvelous Work is yet to come.
