What is the meaning of third heaven in 2 Corinthians 12:2?
The Bible refers to three heavens. We learn in Genesis chapter 1 verses 6 and 7 that God created the firmament. He called this firmament heaven in verse 8. The Sun and Moon were placed in part of it (verses 16 to 18), and birds fly in another part (verse 20). We would typically refer to these two heavens as outer space and our atmosphere. The third heaven (referred to in 2 Corinthians chapter 12 verses 2-4 among other places), would be the spiritual realm where God and the angels reside.
