When they hand you over, do not worry about how you are to speak or what you are to say; for what you are to say will be given to you at that time; for it is not you who speak, but the Spirit of your Father speaking through you.
Do you have times when you have to address something that is important, so you toss and turn all night worrying about what you should say and how you should say it? I suspect we all do that from time to time. However, we have the assurance that the Spirit will provide the words we need. Even in uncomfortable situations we will have the “right” words, if we only ask. Instead of worrying and being anxious Jesus tells us to ask the Spirit to speak through us.
