Three Heavens
There are three heavens described in the Bible: our immediate atmosphere, outer space and the home of God. The first heaven is what is called the firmament or sky that covers the earth. This is the realm of birds and clouds that surrounds the entire earth. The second heaven is where the sun, the stars and the moon reside. This is the space beyond the earth and it covers the entire universe. The third heaven is unseen and is the residence of God, including Jesus Christ. This is where the dead martyrs and the saints are today. This is the location of the throne of God and where the holy angels surrounding His throne sing day and night, Holy, Holy, Holy is the Lord our God. We can conclude that there is such a specific place as the third heaven. It is always spoken of as being above the first and second heaven. In addition, since these first two heavens are actual places we should also conclude that the third heaven is a real place too. There is no reason for us to assume it is symbolic especially since the first two heavens are speaking of known realities.
