Halakhah do Izajasza 41:8

And this is the intention of our rabbis z”l, when they say, “All who judge a judgement truthfully, it’s as if he is a partner with God in the creation of the world,” because God created the world to continue and the wicked who steal and commit acts of violence ruin the world through their actions. And similarly we find regarding the generation of the flood that the decree of their judgement was sealed only because of theft, as it is written, (Genesis 6:11) “For the earth is filled with violence,” and it says after this, (Genesis 6:13) “I will destroy them with the earth”. What emerges is that the judge who breaks the high arms of the wicked keeps the world going and completes the will of the Creator, blessed is His name, who created it to keep going, and it is as if they become partners with the Holy One ,Blessed Be He, in the creation. Abraham our forefather didn’t know God, and He called him (Isaiah 41:8) “My beloved” because he walked in the ways of justice and guided his children, as it is written, (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 God, to do righteousness and justice…” And Moses our teacher a”h, master of all prophets, took advice from Yitro with regards to justice, to establish judges to caution Israel and to command them through justice, and God agreed with this. And Joshua afterwards established a covenant with Israel to serve God, he left his last word as justice, as it is written, (Joshua 24:25) “On that day Joshua made a covenant for the people, and there at Shechem he reaffirmed for them laws and justice.” [This is] because justice is the foundation and the great principle in the service of God, and following [Abraham] have each and every judge judged their generation, and bring them back from their evil ways to service of God to go in the way that Abraham paved to do righteousness and justice, and through this were they [i.e. the Jewish people] were saved from their enemies until Samuel the prophet came, God-faithful, (1 Samuel 7:15-16) “who judged Israel all the days of his life. And he went on a circuit year by year to Bethel, Gilgal, and Mizpah. And he judged Israel in all these places.” And our sages tell us that the path he took one year was not the one he took the next, so that he could turn the hearts of the entire nation toward service of God, and to walk in the way of Abraham our forefather a”h, and he anointed David to be the king of Israel, and he too walked in the ways of God from all that was in front of him, as it is written,(2 Samuel 8:15) “And David did justice and righteousness. (1 Chronicles 11:8) “And Joab restored the rest of the city.” And our sages tell us that in the merit of the justice and righteousness of David, Joab restored the rest of the city, and had his child [Solomon] continue after him, the “Yedid Hashem”, who loved to go in the laws of his father David and would ask from God an understanding, listening heart to judge his people, to understand between good and bad, and it was good in God’s eyes, that which he asked regarding this. And He gave him a wise and understanding heart which has never been before, and no one has been like him since, and all of Israel was afraid of him because they saw that the wisdom of God was in his heart to do justice. And also Jehoshaphat, who took the paths of his father and raised his heart in the ways of God, was strengthened in justice, and he appointed judges in every city, and he said to the judges, “See what you do, for you are not judging for man but for God, and with you shall be justice.” Josiah as well, that Scripture testifies about him, “And no king was like him before, who returned to God with all his heart.” And also the King Messiah, who will be revealed speedily in our days, is praised by Scripture regarding justice, and it is written, (Isaiah 11:4) “And he will judge the destitute with justice, and decide with equity for the meek of the earth…” And according to the greatness of his reward will be the punishment for those who void and pervert it, as it is taught, “Destruction comes to the word based on lack of law and on the perversion of law.” And so did David say, (Psalms 119:121) “I have done justice and righteousness, leave me not to my oppressors.” This implies that without justice, he would have been left in the hands off oppressors. And Jerusalem was only destroyed, and Israel only exiled, because of the neglecting of justice, as it is written, (Isaiah 1:21) “She once was full of justice; righteousness used to dwell in her-- but now murderers.”... And God wants it more than all the sacrifices, as it is written, “Doing righteousness and justice is choicier to God than the zevach offerings.” It does not says “than sin and burnt offerings,” but rather “than zevach offerings.”

That is that He commanded us about loving Him, may He be exalted. And that is that we think about and contemplate His commandments, His statements and His actions until we comprehend Him and derive the greatest pleasure from that comprehension. And that is the love that is obligated. And the language of the Sifrei (Sifrei Devarim 33:1) is, "Since it is stated, 'And you shall love,' I would not know how a man is to love the Omnipresent. [Hence] we learn to say, 'And these things that I command you today shall be upon your heart' (Deuteronomy 6:6) - that through this, you will recognize the One that spoke and the world [came into being]." Behold we have explained to you that comprehension will come to you through contemplation and you will [then] come to pleasure, and perforce the love will come. And we have already clarified that this commandment also includes that we call all people to His service, may He be exalted, and to believe in Him. And that is since when you love a person, you will recount his praises and magnify him, and call on other people to love him. And this is, by way of analogy, the same with true love of Him, may He be exalted: When comprehension of His truth comes to you, you without a doubt call out to the fools and silly ones to know the true knowledge that you know. And the language of the Sifrei (Sifrei Devarim 32:2) is, "'And you shall love the Lord, your God' - cause Him to be loved by the creatures, like your father Avraham (did); as it is stated (Genesis 12:5), 'and the souls that they had made in Charan.'" And it means to say: Like Avraham who loved [God] - as Scripture testifies, "Avraham, who loves me" (Isaiah 41:8), and this was from his great comprehension - to the point that he called people to Him. (See Parashat Vaetchanan; Mishneh Torah, Foundations of the Torah 2.)

It is a positive commandment to love God, may He be blessed, with all one's heart, and all one's soul, and all one's might. As it is said (Deuteronomy 6:5): "You shall love the LORD your God with all your heart and with all your soul and with all your might." The way to love Him is to meditate on His acts until one contemplates them to the degree to which he is able - when the heart is aflame with the love of Him. This is the love which is incumbent upon us. One should direct all of his thoughts toward the love of God, may He be blessed. A person can only love the Holy One, blessed be He from the knowledge with which he knows Him, so in proportion to that knowledge will be the love: if [the knowledge is] small, [the love will be] small; if great, great. Therefore, a person needs to focus himself on understanding and comprehending, through wisdom and known philosophies, the honor of his Master, in proportion to the ability which he has to understand and attain. This is one of the commandments which a person is obligated in at all times, at every moment. Included in this commandment is [the requirement] to bring people close to His service, may He be blessed, and to love Him for what he has created, as our forefather Avraham, peace be upon him, did, as it is said (Genesis 12:5): "And the souls which he created in Haran." Because of this, the Holy One, blessed be He, called Avraham His beloved, as it is said (Isaiah 41:8): "Avraham my beloved."
