I thought your post was rather good as it is always good when
the Lord speaks to us.
It made perfect sense to me so I'll share my perspective with you.
Elect and Restrainer love each other and are therefore united.
Falling away is also interpereted as departing, voyage, leaving heading
for a destination!
So the three things the Lord lumped together, proving to (to me)
the above interpretation is correct, otherwise what the Lord spoke
would make no sense.
