In October of 1988 President Ezra Taft Benson gave a talk entitled "I Testify". Considering this was his final spoken message to the saints in General Conference, this talk could be considered his final testimony. The following is an abridged version of his testimony (read the full article here). I have also made the mp3 audio recording available.
"As a special witness of Jesus Christ, and as His humble servant, it is now my obligation and privilege, as the Spirit dictates, to bear pure testimony and witness to that which I know to be true..."
"I testify that we are the spirit offspring of a loving God, our Heavenly Father... that God reveals His will to all men through the Light of Christ... that throughout the ages God has spoken to His children through His prophets... that a world so wicked that it killed the Son of God soon began killing the Apostles and prophets and so plunged itself into a spiritual dark age... that God the Father and His Son, Jesus Christ, appeared to Joseph Smith... bringing to an end the long night of apostasy... that through the Book of Mormon God has provided for our day tangible evidence that Jesus is the Christ and that Joseph Smith is His prophet... America will be a blessed land unto the righteous forever...""I testify that wickedness is rapidly expanding in every segment of our society. It is more highly organized, more cleverly disguised, and more powerfully promoted than ever before. Secret combinations lusting for power, gain, and glory are flourishing. A secret combination that seeks to overthrow the freedom of all lands, nations, and countries is increasing its evil influence and control over America and the entire world.""I testify that the church and kingdom of God is increasing in strength. Its numbers are growing, as is the faithfulness of its faithful members. It has never been better organized or equipped to perform its divine mission.""I testify that as the forces of evil increase under Lucifer’s leadership and as the forces of good increase under the leadership of Jesus Christ, there will be growing battles between the two until the final confrontation. As the issues become clearer and more obvious, all mankind will eventually be required to align themselves either for the kingdom of God or for the kingdom of the devil. As these conflicts rage, either secretly or openly, the righteous will be tested. God’s wrath will soon shake the nations of the earth and will be poured out on the wicked without measure. But God will provide strength for the righteous and the means of escape; and eventually and finally truth will triumph.""I testify that it is time for every man to set in order his own house both temporally and spiritually... that not many years hence the earth will be cleansed. Jesus the Christ will come again, this time in power and great glory to vanquish His foes and to rule and reign on the earth... I testify to you that a fulness of joy can only come through the atonement of Jesus Christ and by obedience to all of the laws and ordinances of the gospel, which are found only in The Church of Jesus Christ of Latter-day Saints.""To all these things I humbly testify and bear my solemn witness that they are true, and I do so in the name of Him who is the head of this church, even Jesus Christ, amen."
