Does this mean that there are some unbelievers who are children of the devil and can't be saved?
John 8:44
NKJV - 44 You are of your father the devil, and the desires of your father you want to do. He was a murderer from the beginning, and does not stand in the truth, because there is no truth in him. When he speaks a lie, he speaks from his own resources, for he is a liar and the father of it.
