For in his hand are both we and our words; all wisdom also, and knowledge of workmanship.
Read Chapter 7
Augustine of Hippo
AD 430
Since concerning everything that must be explained in the light of faith and love, there are many things to say and many ways in which experts can speak about them, who knows, at the present moment, what would be useful for us to say or to hear, except the one who sees the hearts of all? And who makes us say what should be said, in the right way, if not him in whose hands are both we and all of our words? Therefore, even if one learns everything there is to teach, all that he ever wanted to know and teach, and acquires the ability to speak, as is appropriate to a church leader"when the moment comes to speak, he should remember that what the Lord says is more fitting than all his valid arguments. "Do not worry about how and what you are to say, because what you are to say will be given you in that moment. Indeed, it will not be you who are speaking but the Spirit of your Father who speaks in you." If, then, the Holy Spirit speaks in those who have been handed over to persecution for Christ, why would he not also do so in those who hand over doctrine to those who want to know Christ? - "Christian Instruction 4.15.32"
