What to Tell the Kids?

I was reminded this morning of what I should be teaching my children:

". . .a testimony. . .
That they should. . .teach to their children;
That the generation to come might know, even the children yet to be born,
That they may arise and tell them to their children,
That they should put their confidence in God,
And not forget the works of God,
But keep His commandments. . ."

--Psalms 78:5-6
