Why shouldn't we try to picture Jesus in the flesh in heaven?

Les explains that although Christ the God-man is in heaven at the Father’s right hand, we still should not try to picture Him in the flesh, because God is so far beyond anything we can put together. When we finally enter His presence, however, we will see Him face to face. Les adds that eternity will be so vast that even if billions participate, each individual remains an individual whom God knows personally, and believers will know Him personally. He acknowledges this is mind-boggling, but says the Word teaches it, so he personally believes it.
