If you Soul Travel without God's Permission and the help of his Angels it is likely you won't survive soul Traveling

Why is this?

Because this is God's Universe and Soul Traveling is the domain of Angels to maintain God's universe. So, if you soul Travel without God's permission it is likely you eventually won't survive it. So, when you soul travel with God's permission and with his Angels you take on the role of angel. This is the best way to put this that I can presently think of.

By God's Grace
