In this passage we see three signs that the powers of darkness are at work. One of the frequent signs, that the powers of darkness are at work, is treachery and betrayal. Another sign, that Satan is involved in his characteristic activity, is when in disregard to the counsel of God, we act recklessly, rashly and foolishly. Insulting and demeaning behavior towards others is also a mark of the work of darkness. Other passages mentioned: Mark 14:44; John 13:27-30; Luke 22:31-32; John 8:12.
