II Peter 2:21-22

Is Peter echoing what Jesus just said in that parable? The latter end of that person out of whom a demon has been cast is worse off than it was if it had never been cast out—if the person does nothing; if he is swept clean and put in order but nothing replaces what left, then that person is worse off.

If a person has not known the right way then they cannot be blamed for not following the right way. But if the person has known the right way, then I think the judgment is going to be that there has been a measure of deliberateness in the person's inactivity. That is, they have actually willed it to try to stand still or, not to do something or, simply to drift with the tide. Or simply to accept the blood of Jesus Christ but then not make the effort that is going to be required in order to do what is right. So there is a measure of deliberateness. It is at least the very beginnings of a willful sin and that is the kind that leads to the Lake of Fire.

So a person who is clean by the blood of Jesus Christ and then decides that they are going to just allow themselves to be distracted by what is going on in the world, allow themselves to be distracted by interests other than the main interest that God has put into their life—just allow themselves to have others impact upon them in a way that is detrimental to their own growth and does not really take control over their own life and go toward the Kingdom of God—that person is showing a measure of willfulness in what they have done.
