One point that sincerely struck me from his Dvar Torah, directed to the bar-mitzvah boy, his older brother's youngest grand-son, was as on the following pasuk (Tehilim 24):
The challenge for teaching a child is not just to push them into a spiritual lifestyle, to accept the mission of being Jewish - this is the emphasis of the question of "who will ascend the mountain if Gd?". Rather it should be to teach children how to reside in a spiritual forum, to exist in a world of struggle for balance between the material and spiritual, the modern and the ancient, and the have the tradition and tools present to be an active agent for Hashem.מִי-יַעֲלֶה בְהַר-יְהוָה; וּמִי-יָקוּם, בִּמְקוֹם קָדְשׁוֹ.Who shall ascend into the mountain of the LORD?and who shall stand in His holy place?
Some educators today, or more factualy educational institutions, are focused on the tactics to be religions, to be affiliated, to be passionate, or to be able to daven in the main minyan. Rav Lau's message was to realize that we must have the greater goal ever present.
Reading the rest of the perek of tehillim only strengthens this point:
May we be worthy to raise such a generation.נְקִי כַפַּיִם, וּבַר-לֵבָב: אֲשֶׁר לֹא-נָשָׂא לַשָּׁוְא נַפְשִׁי; וְלֹא נִשְׁבַּע לְמִרְמָה.יִשָּׂא בְרָכָה, מֵאֵת יְהוָה; וּצְדָקָה, מֵאֱלֹהֵי יִשְׁעוֹ.זֶה, דּוֹר דֹּרְשָׁו; מְבַקְשֵׁי פָנֶיךָ יַעֲקֹב סֶלָה.He that hath clean hands, and a pure heart; who hath not taken My name in vainand hath not sworn deceitfullyHe shall receive a blessing from Hashem, and righteousness from the God of his salvationSuch is the generation of them that seek after Him, that seek Thy face, even Jacob. Selah
