Some people welcome change and in fact, thrive on it. I think Velvet and Carl must be like that. Other people resist change and wish that things would stay the same. They get comfortable with the way things are and don't wish to have their boat rocked.
One of the most challenging of changes is when you get a new church calling. We generally accept this as the Lord's will for us and recognize that He must have a reason in His grand plan for our lives to give us a new challenge.
Ken said he was comfortable in his calling as ward mission leader and loved working with the Elders. So just when he gets comfortable, he gets challenged with a new calling--1st assistant in the High Priest group leadership. We're proud of him and know he'll learn to love that too as he gets involved in helping people, albeit older ones than he's used to.
Sheryl loved being the Young Womens president and felt quite badly when they wanted to release her. But she and Jonathan have been given two new joint callings which fit their expertise--ward organists and preparedness specialists. They will learn from these callings and from doing them cooperatively. It will prepare them to be senior couple missionaries some day!
The Andrei got shaken up too. Mike was released as executive secretary and called to be the Young Men's president. And then, so there wouldn't be two presidents in one family, they released Brenda as Primary president and asked her to teach the 15-year olds in Sunday School. The teens will love her and respect her because she's not old fashioned and knows how to communicate with them.

We are proud of you all for accepting these new assignments with enthusiasm. We pray the Lord will bless you as you fulfill them faithfully. I can personally witness to the growth that has come through study and service in the various callings I have had. I know the Spirit prompts you to know what is needed to be done in that calling and fills in to make up for your weaknesses. I also know the Lord loves you for accepting these new callings and helping His work go forward. Just like you promised to do in the Temple!
