John 12:49-50

For I have never spoken on My own initiative or authority, but the Father Himself who sent Me has given Me a commandment regarding what to say and what to speak. I know that His commandment is eternal life. So things I speak, (in accordance with His exact instruction) just as the Father has told Me.

Are we speaking according to the Word and the instruction of God? Do our words speak of eternal life, or are we speaking of death? Our words matter because they will amplify the situation, whether it is a positive or negative experience. If we talk negative comments, the circumstance will stay negative. Only by speaking Faith-filled words and believing them will we be speaking life.
