“Yes, it is as you say,” Jesus replied. “But I say to all of you: In the future you will see the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven.” Matthew 26:64
After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air. And so we will be with the Lord forever. 1 Thessalonians 4:17
Look, he is coming with the clouds, and every eye will see him, even those who pierced him; and all the peoples of the earth will mourn because of him. So shall it be! Amen. Revelation 1:7
Heaven, God’s home, has always been depicted as existing in clouds. Artists understood that heaven was out of our sight and above our earth (Jesus did ascend into the clouds). As one who has flown many times, I can tell you for sure that heaven is not in the clouds. I remember as a kid looking out the window of the plane to see heaven and always being disappointed.
Clouds represent something above the earth, out of reach, separated from our lives. It was not meant to mean a literal destination of heaven.
Heaven is not in the clouds, nor is Jesus riding around on a cloud. The answer is, yes, you would fall through the clouds if you walked through them.
