What you say out loud is your confession and it is your testimony- think about that the next time you open your mouth.
The words you speak out loud are the same words that you (and others) hear - are they building up or tearing down your faith? Are they fighting for or against the enemy? If you can’t think of anything to say that is helpful, then speak God’s word. It is true and it is a mighty weapon!
“So faith comes from hearing, and hearing through the word of Christ.”
Romans 10:17
