My good friend, E. Ray Moore of Exodus Mandate has written a fabulous little book entitled, The Promise of Jonadab: Building a Christian Family Legacy in a Time of Cultural Decline.
I love this book. If you ever wanted to be inspired by a multi-generational view of covenant faithfulness, this story, right out of Scripture, will do the trick! Imagine if you could have such an impact on your family that 240 years later, your descendents were still being faithful to the Lord because of your influence! That was the true example of Jonadab.
You can read more about his life and influence here: http://www.exodusmandate.org/art_jehonadab.htm
I would strong encourage you to pick up a copy of this book for a husband / father that you love. We read this book aloud as a family in our Family Worship time and it was a great blessing to us.
