John 10:28, "And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand."
The verse says they shall never perish which is translated can never be lost. The verse is parallelism in form;
they shall never perish,
neither shall any man pluck them out of my hand.
They reinforce the same idea; you can't be lost.
YEAH! And I'm not even that bright and I can get this. What's the deal around here? :)
