Jesus tells us not to prepare at all and to trust that he will give us the words and wisdom we need. What is important is not that we have a little speech ready but that we remain deeply anchored in the love of Jesus, secure about who we are in this world and why we are here. With our hearts connected to the heart of Jesus, we will always know what to say when the time to speak comes.
For further reflection...
... do not worry about how you will defend yourselves or what you will say, for the Holy Spirit will teach you at that time what you should say.
Luke 12: 11b, 12 (NIV)
