For after your testimony- comes God’s testimony

Doctrine and Covenants 88:89-91
89 For after your testimony cometh the testimony of earthquakes, that shall cause groanings in the midst of her, and men shall fall upon the ground and shall not be able to stand.
90 And also cometh the testimony of the voice of thunderings, and the voice of lightnings, and the voice of tempests, and the voice of the waves of the sea heaving themselves beyond their bounds.
91 And all things shall be in commotion; and surely, men’s hearts shall fail them; for fear shall come upon all people. https://www.lds.org/scriptures/dc-testament/dc/88?lang=eng
