"Prophecy is basically learning how to open our mouths and speak what God is giving us. We are moved by the Holy Ghost. Prophecy is His work, but He chooses to use our voices. He chooses to use our lips. He chooses to use our tongues ... God won't force you to, but you may if you are willing. It's possible. It's permissible. If you are moved by the Spirit of the Living God, you may prophecy".
