As you enter a new appointment you are not beginning a new book. There already exists a book where you are going, and many chapters have been written before you arrived. Rather, you now need to become part of that ongoing story. For that to happen you need to be accepted into the story by the people of the story, you cannot force your way into it. This requires listening, asking questions, trying to understand - getting to know the stories that has become part of the book so far.
At the same time, when you arrive a new chapter is to be written of this ongoing story. A new chapter begins with a blank sheet of paper. It follows on and continues the previous chapters, and yet it will be different. It is an opportunity for a new beginning, a chance to explore where God is leading in this new era.
The important thing to recognise is that you are not the sole author of this new chapter, it is a community exercise. Together with the fellowship to which you are sent, under the guidance of the Holy Spirit, you will be part of writing God's story. You will be able to influence the story to the degree you are open to be influenced by the fellowship and the Spirit.
Finally, a new chapter is to be written in another book - your book. Also here, many chapters have already been written, full of experiences, joy, pain, victories, defeats. While never denying what has gone before, as this is what has made you what you are today, you also need to start on a blank sheet of paper. This means being open for new things, new relationships, and not letting yourself, or your surroundings, be tied unnecessarily down by your past.
It is a new day and a new God-adventure awaits you. Embrace it in faith, let God guide your hand as you write, and may you experience how God will not only guide and sustain you, but surprise you abundantly.
