It has almost become the "theme verse" for homeschooling.  Deut 6:7

and thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thy house, and when thou walkest by the way, and when thou liest down, and when thou risest up

However, in my current thoughts on discipleship, I was thinking about the whole context.  Here it is, in part

Hear, O Israel: Jehovah our God is one Jehovah: ⁵ and thou shalt love Jehovah thy God with all thy heart, and with all thy soul, and with all thy might. ⁶ And these words, which I command thee this day, shall be upon thy heart; ⁷ and thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thy house, and when thou walkest by the way, and when thou liest down, and when thou risest up. ⁸ And thou shalt bind them for a sign upon thy hand, and they shall be for frontlets between thine eyes. ⁹ And thou shalt write them upon the door-posts of thy house, and upon thy gates. 10 And it shall be, when Jehovah thy God shall bring thee into the land which he sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give thee, great and goodly cities, which thou buildest not, ¹¹ and houses full of all good things, which thou filledst not, and cisterns hewn out, which thou hewedst not, vineyards and olive-trees, which thou plantedst not, and thou shalt eat and be full; ¹² then beware lest thou forget Jehovah, who brought thee forth out of the land of Egypt, out of the house of bondage. ¹³ Thou shalt fear Jehovah thy God; and him shalt thou serve, and shalt swear by his name. ¹⁴ Ye shall not go after other gods, of the gods of the peoples that are round about you; ¹⁵ for Jehovah thy God in the midst of thee is a jealous God; lest the anger of Jehovah thy God be kindled against thee, and he destroy thee from off the face of the earth....²⁰ When thy son asketh thee in time to come, saying, What mean the testimonies, and the statutes, and the ordinances, which Jehovah our God hath commanded you?  ²¹ then thou shalt say unto thy son, We were Pharaoh's bondmen in Egypt: and Jehovah brought us out of Egypt with a mighty hand; ²² and Jehovah showed signs and wonders, great and sore, upon Egypt, upon Pharaoh, and upon all his house, before our eyes; ²³ and he brought us out from thence, that he might bring us in, to give us the land which he sware unto our fathers. ²⁴ And Jehovah commanded us to do all these statutes, to fear Jehovah our God, for our good always, that he might preserve us alive, as at this day.

As I re-read this familar passage I can't help but make a few quick observations.

1. Scripture is always before them, and this is a people who don't have printing presses or internet.  God commanded His Word to be before them.  On their hand and on their forehead.  How much more in front of you all the time does that get.  It is to be on your gates and door posts of your house.  I wonder if on your hand would symbolize all you do, on your forehead, all you think, on your gate, all who leave your home, while they are outside the home, and on the door post all who come into your home while they are in your home.  In other words, there isn't a time, place, or activity that isn't bathed in Scripture.  It is in this context that we begin to talk to our children and work with them in discipleship
2. I also couldn't help but notice the similarities between the wealth described for the Jews and the wealth we have in this country.  In the midst of all this wealth we are warned not to forget God.  In the midst of all this weath, even with God's Word everywhere in our lives (hand, head, gate, doorposts), we are still warned not to forget God. 
3. They were commanded to be ready to answer their children's questions about the Law.  God didn't tell them to tell their children, "Because I said so", but to give a detailed explaination as to why they were to obey God.
4. Their children asked "Why are there all these rules and regulations" too, but the Jews had a good answer for them, instead of the cop out answers we sometimes give.

So, what does this mean.  What would does my life look like, and what would it look like if I lived, and I mean truly lived this passage.

I come home from work, and I see the bike (or this time of year) the sled that was left out.  I pull into my driveway, sigh and gear up to go inside.  I am greeted by loud, but happy children (sometimes), or, I am greeted by the problems of the day from the broken hinge to the clogged sink, to the child who disobeyed who needs "Dad's attention".  We eat dinner together as a family, with plenty of fussing about good manners.  Maybe the same happens at your house ("sit straight in your chair", "Don't eat with your fingers", "We pass the potatoes, not reach across the table for them").  After dinner we have family worship, again with plenty of correction about sitting still, paying attention, being sure to sing, not kicking your sister, etc., etc., etc.   Next I complain about their room, and how it isn't clean, and then about how the living room isn't clean, and stay on them until they both are.  Finally, after a little visiting, or playing off to bed.  Now, we have done some things to bring more Scripture into our house.  For example, on our old front door, my lovely wife painted it with the fruit of the Spirit.  We have scripture hanging in our home, including our family "theme verse" of Philippians 4:8.  We do family worship.  The children go to sleep listening to Scripture CD's, but do I really live this verse?  I got to wondering what my evening would look like if I were to apply this passage.  HMMMM.  I have gone long enough here already.  Next post I will tell you what I think it might look like
