Four Greek words translated Heaven:
OURANOS – Sky, Air
OURANOTHEN – From the Sky
EPOURANIOS – Above the Sky
MESOURANEMA – Mist of the Sky
Christ looked up toward Heaven for whence came His power
Matthew 14:19 Mark 7:24 John 17:1 (Matthew 26:39)
Christ ascended up into Heaven
Acts 1:9 And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight.
Stephen viewed up into Heaven to see Christ
Acts 7:54-56 When they heard these things, they were cut to the heart, and they gnashed on him with their teeth. But he, being full of the Holy Ghost, looked up stedfastly into heaven, and saw the glory of God, and Jesus standing on the right hand of God, And said, Behold, I see the heavens opened, and the Son of man standing on the right hand of God.
Paul hints at more than one Heaven
Ephesians 4:10 He that descended is the same also that ascended up far above all heavens, that he might fill all things.)
Paul numbers the Heavens for us (1 Atmosphere, 2 Planets, 3 Abode of God)
2 Corinthians 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.
Even Satan gives us a direction to Heaven
Isaiah 14:12-15 How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations! For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north: I will ascend above the heights of the clouds; I will be like the most High. Yet thou shalt be brought down to hell, to the sides of the pit.
(Isaiah 40:22 It is he that sitteth upon the circle of the earth, and the inhabitants thereof are as grasshoppers; that stretcheth out the heavens as a curtain, and spreadeth them out as a tent to dwell in: )
Note: Astrometry say that there is a void in the sky, Northward where there are no stars.
Peter writes that the Heavens shall pass away
2 Peter 3:10-12 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness, Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?
New Heaven 2 Peter 3:13 Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
John also writes of a New Heaven
Revelation 21:1 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.
God’s Abode doesn’t ever Change! That’s where John was when he wrote Revelation.
