Elijah of the Old Testament was fulfilled by John the Baptist

^{A Marvelous Work and a Wonder}

^{Chapter 13}

^{The Mission of Elijah}

^{Elijah's coming foretold}

<sup>The next major event we will consider in this "restution of all things" (acts 3 :19-21) is the coming of Elijah in fulfillment of Malachi 4:5-6

^{Matthew 11:}

^{11 Truly I tell you, among those born of women there has not risen anyone greater than John the Baptist; yet whoever is least in the kingdom of heaven is greater than he. 12 From the days of John the Baptist until now, the kingdom of heaven has been subjected to violence,  and violent people have been raiding it. 13 For all the Prophets and the Law prophesied until John. 14 And if you are willing to accept it, he is the Elijah who was to come. 15 Whoever has ears, let them hear.}

^{Mark 9:}

^{11 And they asked Him, saying, “Why do the scribes say that Elijah must come first?”}

^{12 Then He answered and told them, “Indeed, Elijah is coming first and restores all things. And how is it written concerning the Son of Man, that He must suffer many things and be treated with contempt? 13 But I say to you that Elijah has also come, and they did to him whatever they wished, as it is written of him.”}

^{Luke 1:}

^{17 He will also go before Him in the spirit and power of Elijah, ‘to turn the hearts of the fathers to the children,’ and the disobedient to the wisdom of the just, to make ready a people prepared for the Lord.”}

^{Notice how the LDS have missing ears, first they miss Matt 11:13 that says John The Baptist was the fullfillment of Malachi} 

^{Matthew 17:10 Then his disciples asked him, “Why do the teachers of religious law insist that Elijah must return before the Messiah comes?”}

^{11 Jesus replied, “Elijah is indeed coming first to get everything ready for the Messiah. 12 But I tell you, Elijah has already come, but he wasn’t recognized, and they chose to abuse him. And in the same way they will also make the Son of Man suffer.” 13 Then the disciples realized he was talking about John the Baptist.}

 Acts 3:19-21 says "the times of refreshing" and the "times of restitution [i.e. restoration] of all things" will come when God sends Christ back at the second coming. Christ is the one who restores all things and brings the refreshing, so this is a prophecy yet to be fulfilled! As a result of Adam's sin, not only man, but all creation was cursed (Gen. 3:17; Rom. 8:19-23). 

"But now we see not yet all things put under Him" (Heb. 2:9a), and not until Christ's return in glory will there be a "restitution of all things which God hath spoken by the mouth of all his holy prophets since the world began" (Acts 3:21). 

Luke 7:28

For I say unto you, Among those that are born of women there is not a greater prophet than John the Baptist: but he that is least in the kingdom of God is greater than he.

Joseph Smith's establishment of the LDS Church did not fulfill this.
