What are the three heavens mentioned in Scripture?
Scripture mentions three heavens. The first heaven is the atmosphere, where the birds fly. The second heaven is space. The third heaven is the very abode of God, which Paul speaks of entering in Corinthians. These are the three terms of heaven used in Scripture.
Les explains that the firmament God called heaven is the atmosphere, and he notes Scripture speaks of three heavens. The first heaven is the atmosphere, the realm of the birds of the heaven. The second heaven is space. The third heaven is the very abode of God, or heaven as we normally think of it; Paul speaks of his own experience of entering into the third heaven in Corinthians. Les also connects the divided waters to a vapor belt above the atmosphere, which could be in the first or even the second heaven.
