Jehovah knew that one of the dominant traits of humankind is forgetfulness. Another suggestion that may prove helpful in our efforts to secure a history of righteous living for our children's' children would be historical documents. This could include a well worn Bible with all the underlining, side notes, and old orders of worship slid between the pages revealing a life long dependence and respect for the Word of God. A journal recording spiritual reflections, written prayers, and messages to the family would have a significant impact on the generations to come. This would enable them to experience something precious few of us will ever have - a chance to know something substantial about our ancestors.
Books are great to pass down.
A library representing a life long pursuit by a patriarch or matriarch to know God would definitely have a better chance of godly influence than a china pattern or Persian rug. Old letters, notes and cards hold a strong appeal. But when it is an ancestor's, well, then it is OK and still as interesting. If this old correspondence contained the sharing of ideas, the praise to God for answered prayers, the godly counsel to an inquirer, or a thank you for unselfish hospitality, the reader is introduced to a life that shined for God. The effect cannot be calculated.
