“Only take care, and keep your soul diligently, lest you forget the things that your eyes have seen, and lest they depart from your heart all the days of your life. Make them known to your children and your children’s children” (Deuteronomy 4:9, ESV)….
It has often been said that the teacher learns more than the student. Put another way, the best way to learn something, or remember something, is to teach it to others. Deuteronomy 4:9 seems to support that theory. The people of Israel are to make known the deeds of the Lord to their children. In the act of teaching these things to their children, they themselves will be constantly reminded. The one who teaches others is far less likely to forget than the one who keeps his knowledge to himself.
The other reliable way for remembering is to put our knowledge to use. The person who uses his mechanical, mathematical, or biblical knowledge on a daily basis is unlikely to forget that knowledge. The person who merely tucks knowledge away in a corner of the brain is, on the other hand, likely to find that knowledge difficult to locate. Again, this is confirmed in scripture.
“What you have learned and received and heard and seen in me—practice these things, and the God of peace will be with you” (Philippians 4:9, ESV). There is no promise of God’s presence to those who merely hear and see, but to those who also “practice.”
If you are one of those people who feels that not much of what has been heard has been retained, maybe it is time to try a more active approach. Instead of merely listening, put what you hear into practice. Instead of merely learning, teach someone.
