Matthew 12:45
Then it goes and takes with it seven other spirits, more evil than itself, and they reenter [the body] and [begin to] live there, so that the latter state of that person becomes worse than the former [state]. It will be the same way with the people of this evil generation."
John 5:14
Later on Jesus found the man in the Temple, and said to him, "Look, you have been made well; stop sinning or else something worse [i.e., than the handicap you had] will happen to you."
2 Peter 2:20
For if people who have escaped from the defiling practices of the world by coming to know our Lord and Savior Jesus Christ, become tangled up in them again, and are overcome by them, these people are worse off than before they were converted.
