Scriptures and in fact human experiences have shown how powerful the spoken word, that is confessions, can work for man’s good. However, they may be used as whips against men. The book of Job identifies it as the scourge of the tongue, thus, the words of men can plant weeds in the garden of your life upon which you have planted words expectantly. 

Nonetheless, Isaiah says you can condemn such negative use of the tongue and show them to be wrong, thus exempt yourself from their operations. There is a way in Jesus Christ.
