Not that I know of.
But if there was, what would that mean to you?That Hebrew passage I quote ...
Hebrews 6:4 For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost,
Hebrews 6:5 And have tasted the good word of God, and the powers of the world to come,
... goes on to say that, since it's impossible for Christ to come back and die again on the Cross -- (remember why Moses was not allowed to enter the Promised Land?) -- a person who is saved is saved eternally.
Getting saved, then losing it would mean that Jesus would have to come back and die again, just for that person.
You mentioned (or hinted, I can't remember) that you were saved at one time, but now aren't.
If that is true, then you're in for a big surprise when you die.
In other words, I believe: once saved, always saved.
