Heaven
The Bible says that God - the Uncreated Creator of all things visible and invisible - dwells in unapproachable light accompanied by cherubim, seraphim, archangels, angels and the company of God's children whose names are recorded in The Book of (Eternal) Life.
In The Book of Revelation the elderly apostle John describes visions of heaven beyond anything human beings could imagine or see.
In 2 Corinthians 12:2-4 Paul talks of being taken up to "The Third Heaven" he calls Paradise in an out-of-the body experience, where he saw things too wonderful to be expressed in words.
The Cosmos
The cosmos is the invisible area between heaven, including our universe, and the physical world inhabited by supernatural forces of good (God's forces) and evil (Satan, his fallen angels and demonic spirits). It is the unseen battleground of the spiritual warfare that is taking place every moment for world domination and Satan's attempts to take over God's throne.
The World
Our world is part of God's creation of the visible universe. It is the battleground for both the natural and the supernatural warfare being waged by Satan's forces against God.
