Sforno on Deuteronomy 6:24/ספורנו על דברים ו׳:כ״ד

1ויצונו ה' לעשות את כל החקים האלה, in order to make us ready by means of their observance,

2ליראה את ה' אלוקינו, this is the result of acquiring a measure of understanding of His greatness; all of this G’d wanted us to appreciate לטוב לנו כל הימים, for He desires to confer goodness, love, He has no egotistical motives. לחיותנו כהיום הזה. To keep us alive as of this day.
