The principal words so translated are shamayim, from “the heights,” and οὐρανός. They are used in a variety of senses: as
It is important to see that, in forming the present system of this world, God made a heaven to this earth, so that the earth should be ruled from heaven. The blessing of the earth, either materially or morally, depends upon its connection with heaven. This blessing will be full when the kingdom of the heavens is established in the Son of Man, and He will come in the clouds of heaven (Psa. 68:32,3532Sing unto God, ye kingdoms of the earth; O sing praises unto the Lord; Selah: (Psalm 68:32)
35O God, thou art terrible out of thy holy places: the God of Israel is he that giveth strength and power unto his people. Blessed be God. (Psalm 68:35)
). It is the place of angelic power, “the principalities and powers in the heavenly places” being angelic, Satan and his angels, though fallen, still being among them (Job 1:66Now there was a day when the sons of God came to present themselves before the Lord, and Satan came also among them. (Job 1:6); Job 2:11Again there was a day when the sons of God came to present themselves before the Lord, and Satan came also among them to present himself before the Lord. (Job 2:1); Rev. 12:7-97And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels, 8And prevailed not; neither was their place found any more in heaven. 9And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him. (Revelation 12:7‑9)).
That there are various heavens is evident; Satan cannot have entrance into the glory, and Paul speaks of being caught up into the third heaven (2 Cor. 12:22I 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 Corinthians 12:2)); and the Lord Jesus passed through the heavens, and we read of “the heaven of heavens” (Deut. 10:1414Behold, the heaven and the heaven of heavens is the Lord's thy God, the earth also, with all that therein is. (Deuteronomy 10:14); 1 Kings 8:2727But will God indeed dwell on the earth? behold, the heaven and heaven of heavens cannot contain thee; how much less this house that I have builded? (1 Kings 8:27)). Very little is said of the saints going to heaven, though their citizenship is there now (Phil. 3:2020For our conversation is in heaven; from whence also we look for the Saviour, the Lord Jesus Christ: (Philippians 3:20)); but they are to be where Jesus is, and He went to heaven, and prepared a place for them. In the Revelation the four and twenty elders are seen in heaven sitting on “thrones.” To Him that sitteth on the throne, and to the Lamb be glory forever and ever. Amen. Believers “look for NEW HEAVENS and a new earth, wherein dwelleth righteousness” (2 Pet. 3:1313Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness. (2 Peter 3:13); Rev. 21:11And 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. (Revelation 21:1)).
