Dear [NAME],
Thank you so much for speaking at our recent church service. There is no doubt in our minds that God sent you to us and that you delivered the message that He gave you. Your words were truly inspiring and the message you presented was very obviously inspired by God.
You were kind to share your time and talent with our congregation, and we are very grateful.
Thank you for the commitment you have made to God in following His call. Truly it is a blessing to many people.
Again, thank you for your testimony and the witness you are in His name.
In His Name,
