The problems of life are rooted in negative talk that comes from our very own mouth instead of agreeing with God's word for what they need!
How often do you hear someone talk like this: "There's a cold going around and I'm going to catch it," or "Bob from accounting is more qualified for the job he will probably get it." This is not what they want, but it is what they speak.
How about this one? "I just can't understand my child! He (or she) will never amount to anything!"
Do ya know what's gonna happen here right? they are going to get what they keep saying with their mouths.
Exactly what they say. They will "reap what they sow" and experience what they don't want because "life and death are in the power of the tongue" (Proverbs 18:21).
God wants us to partner with Him to bring His will about in our lives and on this earth.
