You don't need to ask him, but don't be such a prig you won't read his words. You might learn something, like your strength alone is not enough. Return of an Unclean Spirit
Luk 11:24 When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest; and finding none, he saith, I will return unto my house whence I came out.
Luk 11:25 And when he cometh, he findeth it swept and garnished.
Luk 11:26 Then goeth he, and taketh to him seven other spirits more wicked than himself; and they enter in, and dwell there: and the last state of that man is worse than the first.
