Where would he go? Past the clouds and into space? Past the moon, Jupiter, Saturn? Since a rocket flying up takes you into one direction of the universe, is heaven in one direction because Jesus flew up into one direction?
If heaven is not “up above” but in a different dimension towards which one can teleport, why would Jesus create such a misconception by flying up above the atmosphere, only to magically disappear and teleport to that different dimension? Isn’t that a little deceptive?
Or perhaps this was a way for prescientific people, who believed heaven was literally above the clouds (Job 22:14/Isaiah 40:22/Amos 9:6) to write the story of Jesus?
