I think that every Christian who is active in his/her community should have this book. It is concise and thorough. One never knows what opportunity will present itself; To witness, to comfort, and/or to pray. This book helps to be ready for these occasions.
I presented this as a gift to a friend of mine who is also going into the ministry field, and I felt that it would help him when he needed to perform a special service such as a wedding, a funeral or baptism, and it would help guide him in his endeavors. I do recommend it
