David,I agree with you that Malachi 4:5,6 has already been fulfilled because our Lord Himself said so in Matt 17:12-13Matt 17:12-13But I tell you, Elijah has already come, and they did not recognize him, but have done to him everything they wished. In the same way the Son of Man is going to suffer at their hands.""Then the disciples understood that he was talking to them about John the Baptist."Luke 1:17 explains how John the Baptist would fulfill Malachi 4:5,6:"And he will go on before the Lord, in the spirit and power of Elijah, to turn the hearts of the fathers to their children and the disobedient to the wisdom of the righteous--to make ready a people prepared for the Lord."The following scriptures prove that Enoch and Elijah died just like any other human being, and they are asleep in the Lord until the first resurrection happens when our Lord returns:John 3:13 No one has ever gone into heaven except the one who came from heaven--the Son of Man.Ps 89:48 What man can live and not see death, or save himself from the power of the grave? SelahHeb 9:27 Just as man is destined to die once, and after that to face judgment,The following scripture talks about how “we fly away” at the end of our days, but certainly no one believes we literally “fly away” ….. we realize that this is the author’s poetic way of saying we experience death.Ps 90:10The length of our days is seventy years--or eighty, if we have the strength; yet their span is but trouble and sorrow, for they quickly pass, and we fly away.The two witnesses will be present-day saints who will come in the power and spirit of Moses and Aaron (and not as Moses and Aaron) to ask the anti-Christ to stop persecuting God’s people and set them free.Maria Z.
