In order to understand the levels of wording that Jesus used, you need to be outside of this dimension, outside of time and space. You’re limited by time and space in the material realm.
The faster you move towards the speed of light the bigger you get, the heavier you get. So you can never get outside of this dimension as a physical being.
That’s why you have to be spirit. You can live outside time and space as long as you’re spirit.
This is only a small portion of the teaching, “Entering the Spiritual Dimensions“.
