Gospel Preached to a Witness over the Nations, End Comes

"I shall read the 24th chapter of Matthew..."And it will be preached, the Gospel of the kingdom, in the whole world, to a witness over all people: and then will the end come." I will now read it in German [which he did, and many Germans who were present said he translated it correctly].  The Savior said when these tribulations should take place, it should be committed to a man who should be a witness over the whole world: the keys of knowledge, power and revelations should be revealed to a witness who should hold the testimony to the world. The old German translators are the most nearly correct-most honest of any of the translators; All the testimony is that the Lord in the last days would commit the keys of the Priesthood to a witness over all people (One Mighty and Strong, saith the Lord). I have read it precisely as the words flowed from the lips of Jesus Christ. John the Revelator saw an angel flying through the midst of heaven, having the everlasting Gospel to preach unto them that dwell on the earth. ...great wars, famines, pestilence, great distress, judgmentsare ready to be poured out on the inhabitants of the earth. John saw the angel having the holy Priesthood, who should preach the everlasting Gospel to all nations. God had an angel-a special messenger-ordained and prepared for that purpose in the last days. Woe, woe be to that man or set of men who lift up their hands against God and His witness in these last days: for they shall deceive almost the very chosen ones! (Joseph Smith, TPJS p.364-365)
