One of my favorite books, The Holy Spirit’s Interpretation of the New Testament, by Regina Dawn Akers, offers a beautiful description of the teacher and the student, or as within 12 Step recovery, the sponsor and the sponsee.
“The teacher is a student that practices all that he teaches, knowing fully that the message he shares is also for him. In this way anyone may be a teacher of My Word, for anyone may choose to be the student, and the student is the teacher. For the teacher comes through the student in order that the student may learn.” ~ from NTI Luke, Chapter 9
Remember; then that what you say to others you are be saying to yourself. This extends to your actions too. An offering of kindness to someone is an offering of kindness to you. Therefore, be aware and mindful of what you say and do.
