'Helpful' in the Bible

Everything is permissible for me, but not all things are beneficial. Everything is permissible for me, but I will not be enslaved by anything [and brought under its power, allowing it to control me].

All things are lawful [that is, morally legitimate, permissible], but not all things are beneficial or advantageous. All things are lawful, but not all things are constructive [to character] and edifying [to spiritual life].
