Proverbs 6:2
Thou art snared with the words of thy mouth, thou art taken with the words of thy mouth.
Sometimes we say things we don’t mean, and they just pop out of the mouth, but they started with a thought. If the devil can get us to speak a negative thought, he can set laws into motion and make it come to pass. If he can get us to talk doubt and unbelief, then we get unfulfilled prayers. The words we speak are essential and can transform our lives and mind. We just need to be careful to make sure what we are saying is working for us and not against us.
