I thought all along, when I was still a child, that there were seven heaven up above us. The Scripture mentioned that there are only three (3), the highest is called as the third heaven.
2 Cor 12:2 I knew a man in Christ above fourteen years ago, (whether in the body, I cannot tell; or whether out of the body, I cannot tell: God knoweth;) such an one caught up to the third heaven.
2 Cor 12:4 How that he was caught up into paradise, and heard unspeakable words, which it is not lawful for a man to utter.
The third heaven where Saint Paul was caught up is also the paradise talked about by Jesus to the other man nailed on the cross beside Him.
Lk 23:43 And Jesus said unto him, Verily I say unto thee, To day shalt thou be with me in paradise.
This is the place where God the father dwell. Jesus told this to His Apostles.
Jn 14:2 In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you.
Jn 14:3 And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also.
The second heaven is in between the third heaven and the heaven that can be seen by our naked eye.
Mk 13:25 And the stars of heaven shall fall, and the powers that are in heaven shall be shaken.
If the power that are in the second heaven are shaken, much more to those in power underneath.
Lk 21:26 Men's hearts failing them for fear, and for apprehension of those things which are coming on the earth: for the powers of heaven shall be shaken.
Heb 12:26 Whose voice then shook the earth: but now he hath promised, saying, Yet once more I shake not the earth only, but also heaven.
The second heaven and the heaven underneath shall be removed as it is both shaken.
Heb 12:27 And this word, Yet once more, signifieth the removing of those things that are shaken, as of things that are made, that those things which cannot be shaken may remain.
Retaining only the heaven not shaken where God and the Son dwell. The third heaven called Paradise.
Heb 12:28 Wherefore we receiving a kingdom which cannot be moved, let us have grace, by which we may serve God acceptably, with reverence and godly fear.
Let not your heart and mind be troubled.
Jn 3:13 And no man hath ascended to heaven, but he that came down from heaven, even the Son of man who is in heaven.
Even the Apostles who died in spreading the gospel of Christ are not yet in heaven.
Heb 11:37 They were stoned, they were sawn asunder, were tempted, were slain with the sword: they wandered about in sheep-skins, and goat-skins; being destitute, afflicted, tormented;
Heb 11:38 (Of whom the world was not worthy:) they wandered in deserts, and in mountains, and in dens and caves of the earth.
Heb 11:39 And these all, having obtained a good report through faith, received not the promise:
Heb 11:40 God having provided some better thing for us, that they without us should not be made perfect.
The living and the dead will have to wait for the coming of Jesus, when the mansions that he prepared are all ready for us to dwell. Remember, they (the Apostles, including Mary) without us should not be made perfect.
Rom 1:25 Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
