BOOK OF MORMON
Perhaps one of the most famous and oft-read final testimonies comes from the prophet Moroni:
Behold, I would exhort you that when ye shall read these things, if it be wisdom in God that ye should read them, that ye would remember how merciful the Lord hath been unto the children of men, from the creation of Adam even down until the time that ye shall receive these things, and ponder it in your hearts.
And when ye shall receive these things, I would exhort you that ye would ask God, the Eternal Father, in the name of Christ, if these things are not true; and if ye shall ask with a sincere heart, with real intent, having faith in Christ, he will manifest the truth of it unto you, by the power of the Holy Ghost.
And by the power of the Holy Ghost ye may know the truth of all things.

Another prophet with a powerful testimony, which he left for posterity in the scriptures, comes from Nephi:
And now, my beloved brethren, and also Jew, and all ye ends of the earth, hearken unto these words and believe in Christ; and if ye believe not in these words believe in Christ. And if ye shall believe in Christ ye will believe in these words, for they are the words of Christ, and he hath given them unto me; and they teach all men that they should do good.
And if they are not the words of Christ, judge ye—for Christ will show unto you, with power and great glory, that they are his words, at the last day; and you and I shall stand face to face before his bar; and ye shall know that I have been commanded of him to write these things, notwithstanding my weakness.
And I pray the Father in the name of Christ that many of us, if not all, may be saved in his kingdom at that great and last day.
And now, my beloved brethren, all those who are of the house of Israel, and all ye ends of the earth, I speak unto you as the voice of one crying from the dust: Farewell until that great day shall come.
And you that will not partake of the goodness of God, and respect the words of the Jews, and also my words, and the words which shall proceed forth out of the mouth of the Lamb of God, behold, I bid you an everlasting farewell, for these words shall condemn you at the last day.
For what I seal on earth, shall be brought against you at the judgment bar; for thus hath the Lord commanded me, and I must obey. Amen.
Paul's powerful testimony nearly persuaded King Agrippa to become a Christian:
Having therefore obtained help of God, I continue unto this day, witnessing both to small and great, saying none other things than those which the prophets and Moses did say should come:
That Christ should suffer, and that he should be the first that should rise from the dead, and should shew light unto the people, and to the Gentiles.
Of course, one of the most powerful witnesses we could ever have is from the Savior Himself. In his last public testimony, before He fulfilled the prophecy of riding into Jerusalem on a young colt, He said the following:
Jesus cried and said, He that believeth on me, believeth not on me, but on him that sent me.
And he that seeth me seeth him that sent me.
I am come a light into the world, that whosoever believeth on me should not abide in darkness.
And if any man hear my words, and believe not, I judge him not: for I came not to judge the world, but to save the world.
He that rejecteth me, and receiveth not my words, hath one that judgeth him: the word that I have spoken, the same shall judge him in the last day.
For I have not spoken of myself; but the Father which sent me, he gave me a commandment, what I should say, and what I should speak. And I know that his commandment is life everlasting: whatsoever I speak therefore, even as the Father said unto me, so I speak (John 12, 44-50).
