I understand ‘the heart’ to refer to the innermost aspect of our being, the spirit that is in us. As such, there is then a dimensional variable we in our present state cannot sense. At the gathering unto Christ in the air, we will have been created a new spacetime being with the fourth variable of spatial incorporated in our physical makeup, such that we too will be able to enter a sice-sided room without using a door or window.
a six sided room ... very bad eyes and old fingers.
We will also be able to travel, faster than the speed of light, to any place in the Universe..............
