Hello Billy,
Heaven is where ever Jesus is. Jesus is Coming to earth, thus the Second Coming. God brought His Presence to Earth back in Moses Day, and resided in the stone temple or tent. Jesus is bringing His Presence to earth, in a new and spectacular way) and He will reside in the body of His Church, on earth. So yes, I do not know where those 'rapture' guys, who are leaving earth, are going?
Through apparitions and locutions from Jesus and the Blessed Mother, Jesus has given us His Divine Mercy Feast Day, Chaplet of Divine Mercy, along with the Sacrament of Reconciliation. We are to purify ourselves, as the Body of the Church, in preparation for the 'Wedding Day of the Lamb', where we will enter into this new marital bond with Jesus. In Jesus' parable of the Wedding Feast, he talks about this 'Wedding Garment', that Jesus has recently given us in His Divine Mercy Feast Day, initiated in the year 2000.
God Himself is going to protect Christ's Bride, the Church, through the 'Three Days of Darkness' and to Her 'Wedding Day with the Lamb', on the third day, when the darkness lifts. Apparitions are indicating that 75% of world population perishes and is thrust into hell during the 'Three Days of Darkness'. What Christians call 'rapture', really happens on earth, where Jesus Comes to us. Jesus will send forth massive miracles, signs and wonders, within the body of His Church, and the nations will stream to Christ's Church through the gates of Baptism.
Matthew 22:1
Jesus again in reply spoke to them in parables, saying, 'The kingdom of heaven may be likened to a king who gave a wedding feast for his son. He dispatched his servants to summon the invited guests to the feast, but they refused to come. A second time he sent other servants, saying, 'Tell those invited: 'Behold, I have prepared my banquet, my calves and fattened cattle are killed, and everything is ready; come to the feast.'' Some ignored the invitation and went away, one to his farm, another to his business. The rest laid hold of his servants, mistreated them, and killed them. The king was enraged and sent his troops, destroyed those murderers, and burned their city. Then he said to his servants, 'The feast is ready, but those who were invited were not worthy to come. Go out, therefore, into the main roads and invite to the feast whomever you find.' The servants went out into the streets and gathered all they found, bad and good alike, and the hall was filled with guests. But when the king came in to meet the guests he saw a man there not dressed in a wedding garment. He said to him, 'My friend, how is it that you came in here without a wedding garment?' But he was reduced to silence. Then the king said to his attendants, 'Bind his hands and feet, and cast him into the darkness outside, where there will be wailing and grinding of teeth.' Many are invited, but few are chosen.
Revelation 21:9 The New Jerusalem.
One of the seven angels who held the seven bowls filled with the seven last plagues came and said to me, "Come, I will show you the woman who is the bride of the Lamb." He carried me away in spirit to the top of a very high mountain and showed me the holy city of Jerusalem coming down out of heaven from God. It gleamed with the splendor of God. The city had the radiance of a precious jewel that sparkled like a diamond. Its wall, massive and high, had twelve gates at which twelve angles were stationed. Twelve names were written on the gates, the names of the twelve tribes of Israel. There were three gates facing east, three north, three south, and three west. The wall of the city had twelve courses of stones as its foundation, on which were written the names of the twelve apostles of the Lamb.
The one who spoke to me held a rod of gold for measuring the city, its gates, and its wall. The city is perfectly square, its length and its width being the same. He measured the city with the rod and found it twelve thousand furlongs in length, in width, and in height. Its wall measured a hundred and forty-four cubits in height by the unit of measurement the angel used. The wall was constructed of jasper; the city was of pure gold, crystal clear. The foundation of the city wall was ornate with precious stones of every sort: the first course of stones was jasper, the second sapphire, the third chalcedony, the fourth emerald, the fifth sardonyx, the sixth carnelian, the seventh chrysolite, the eighth beryl, the ninth topaz, the tenth chrysoprase, the eleventh hyacinth, and the twelfth amethyst. the twelve gates were twelve pearls, each made of a single pearl; and the streets of the city were of pure gold, transparent as glass. I saw no temple in the city, The Lord God the Almighty, is its temple he and the Lamb. The city had no need of sun or moon, for the glory of God gave it light, and its lamp was the Lamb. The nations shall walk by its light; to it the kings of the earth shall bring their treasures. During the day its gates shall never be shut, and there shall be no night. The treasures and wealth of the nations shall be brought there, but nothing profane shall enter it, nor anyone who is a liar or has done a detestable act. Only those shall enter whose names are inscribed in the book of the living kept by the Lamb.
