D&C 77

 Concerning the seventh seal, the Prophet Joseph Smith was asked - 

"Q. What are we to understand by the sounding of the trumpets, mentioned in the 8th chapter of Revelation?

A. We are to understand that as God made the world in six days, and on the seventh day he finished his work, and sanctified it, and also formed man out of the dust of the earth, even so, in the beginning of the seventh thousand years will the Lord God sanctify the earth, and complete the salvation of man, and judge all things, and shall redeem all things, except that which he hath not put into his power, when he shall have sealed all things, unto the end of all things; and the sounding of the trumpets of the seven angels are the preparing and finishing of his work, in the beginning of the seventh thousand years—the preparing of the way before the time of his coming."  (Doctrine and Covenants 77:12)

And - 

"Q. When are the things to be accomplished, which are written in the 9th chapter of Revelation?

A. They are to be accomplished after the opening of the seventh seal, before the coming of Christ."  Doctrine and Covenants 77:13)

We have recently heard many warnings recently that we are to prepare for the second coming of the Savior.  Many temples are being built.  I personally feel that He is finishing His work in preparation for His coming.  Which would suggest in my mind, the 7th seal has been opened.
