LIkutei Halachos - Hilchos Tefillin 5:15
It is said about Mashiach, "Today I have given birth to you." (Tehillim 2:7) For, Mashiach will completely merit this concept, which relates to longevity. Every moment he will begin to live anew, as if he were born today, which is an aspect of, "Today, I have given birth to you." Mashiach will achieve the concept of being above physical time, as Rabbeinu z"l explains on the above mentioned passuk. Look inside Likutei Moharan I Torah 61.
