Bible Exposition of March 28, 2021 - "Is Heaven Real?"
Heaven is real because Gen. 1:6-8 is where God called the firmament heaven. The word firmament simply means, an expanse, or the visible arch of the sky. But there are other heavens. The Bible mentions three heavens in 2Cor. 12:2. And verse 4 refers to the 3rd heaven as the paradise. The paradise is where God and our Lord Jesus Christ live.
The 2nd heaven is the space where we have the galaxies. The space is so vast that it's beyond the knowledge of man. Halley's comet travels in space and returns to the earth every 25 years. This means that none can see this comet more than two times in his lifetime.
