What are the biggest obstacles to never dying here on earth?

I would say the biggest obstacle for people is psychological.

It's like this:

If you don't believe you have legs you cannot walk.

If you don't believe you have hands you cannot do anything with your hands including feed yourself.

So, you have to believe that it is potentially possible to never die in order for that to actually happen.

By the way I'm not asking you to believe that you will never die. This is entirely up to you to do this because it's about your personal relationship with LIFE and GOD and how you relate to yourself in relation to the entire universe and time and space and Heavens and all that.

However, I can tell you that I now believe it is possible for me to never die here on earth.

Will this happen. Maybe. Why?

Because Saint Germain came to me personally in the 1970s and said to me:

"If you live to be 100 you will see 500"

Though he said more than this  maybe there is where we all should start.

Why?

Because life is lived ONE MOMENT AT A TIME.

To do anything else would prevent your physical immortality from actually happening.

This is something I have discovered too.

By God's Grace

So, it's living in the Eternal Moment of Now that you and I become physically immortal here on earth:

(POTENTIALLY).
