Musar sobre Génesis 26:5

How pleasant is the Musar of Love. Anyone whom Hashem loves, God brings down upon them suffering. You find three good gifts that God gave to Israel; and they were only given by way of suffering. These are them: Torah, the Land of Israel, and the World to Come.

Now, when these three powers are gathered within a man, his soul is drawn by its very nature to love the Creator, blessed be He. When he loves Him, his service will be completely perfect. For from that love there will come fear, for whomsoever a man loves, he also fears. It is also possible for a man to fear someone he does not love. Therefore, I say that fear is contained within love, but love is not contained within fear. Now, we have found that the service of our father, Abraham, peace be upon him, was completely perfect, for it says concerning him (Genesis 18:19), “For I have known him, to the end that he may command his children and his household after him, that they may keep the way of the Lord.” This is clear proof of his great righteousness. Moreover, the Creator, blessed be He, testified concerning him after his death, when he said (ibid., 26:5), “Because Abraham hearkened to My voice, and kept My charge, My commandments, My statutes and My laws,”.

Rashi tells us in Genesis 26,5, that the term חק is used in the Torah when the legislation is such that it offers Satan an opportunity to challenge its logic. He quotes the prohibition of eating pork as an additional example.
