Here is an excellent resource at a timely time. The Christian Counseling and Education Foundation has released the booklet, Family Feuds, in a shorter format, online, for your assistance at this time of the year, when families are often together and not getting along. Read this introduction: 
Christmas is coming and that means family get-togethers. But these celebrations are not always a picture postcard of family bliss. For some, these gatherings are dreaded and avoided when possible. Why is that? Why is it so hard to get along with the people you grew up with? Is there any hope that old, hurtful patterns can be changed? In this booklet, Tim Lane writes about these challenges and how through your relationship with Christ you can learn how to love your family and reach out to them in concrete and practical ways.
I encourage you to read the whole article. Tim Lane gives some practical strategies for dealing with family difficulties.
I Commend Joy!
