There are certain ways a man should speak, as believers there is a way you should speak, because the way you speak will determine if the door of utterance has been given or not. For a man to clearly speak and declare the mystery of God, a door of utterance must be opened. When the door of utterance is opened, it also opens another door which is the door of faith for unbelievers, for them to believe. Faith will be stirred up on you after hearing the testimonies of Jesus Christ. The man who the door of utterance has been opened up to speaks with authority, it allows him to open his mouth boldly to speak the word of God. The door of God breaks every chain, when the door of utterance is opened to a man, his word carries grace.
When the door of utterance is opened to a man, he will teach with authority and power. The door of utterance comes with amazement. It transforms a man from being ordinary to extraordinary and from being mortal to immortal. The door of utterance brings divine recognition, it brings fame. You will be known by people all over the world, the gospel spreads through those that take the Father’s business serious. Every door has its own key, the only key for this door to be opened is prayer, the Apostles prayed in Acts 4:31 and this opened the door of utterance to witness Christ to the lost. The assignment of the gospel is for every believer, either you are called or not. When you have alternative to God, you cannot have great faith.
If the door of utterance is not opened, fear will set in. The door must be opened unto you for God to speak through it.
