Matthew 10:19-20 (New International Version)
19But when they arrest you, do not worry about what to say or how to say it. At that time you will be given what to say, 20for it will not be you speaking, but the Spirit of your Father speaking through you.
I love this verse! I re-discovered it the other day when researching "Worry". How awesome are these words to remind us how to let go in a situation and let God. Stay quiet and wait for the words rather than trying to force them. I love this.
