The ten commandments will never be superseded for all eternity. You've misinterpreted the verses you've put up. The two love commandments that you posted simply summed up the ten commandments. The first four commandments are about Love of God and the next six are about love for each other. All the ten commandments hang upon these two principles of love. Love for God and love for people. Christ was saying that love is the fulfilling of the law. If one loves Christ supremely with heart, soul, and mind, he will obey the first four commandments that have to do with our duty to God. He will not take God’s name in vain, worship other gods, etc. If one loves his neighbour as himself, he will obey the last six commandments that relate to our duty to our fellow men. He will not be able to steal from his neighbour, lie about him, etc. Love will lead to obeying or fulfilling all the law.I believe the ten commandment has already been superseded
Mark 12:30-31 New King James Version (NKJV)
30 And you shall love the Lord your God with all your heart, with all your soul, with all your mind, and with all your strength.’ [a]This is the first commandment. 31 And the second, like it, is this: ‘You shall love your neighbor as yourself.’ There is no other commandment greater than these.”
Galatians 5:14 New King James Version (NKJV)
14 For all the law is fulfilled in one word, even in this: “You shall love your neighbor as yourself.”
Even the sabbath is not a requirement anymore.
Also Matthew 22:37–40 commands us to love God and to love our neighbours, ending with the words, "On these two commandments hang all the Law and the Prophets." The scripture you posted above does not replace the ten commandments. You would have to ignore everything that the Bible says about the ten commandments to come to your conclusion.
This response is going to be a bit long because I want to post scripture from the Bible about the ten commandments and there is a lot of it.
Jesus said, “It is easier for heaven and earth to pass away than for one tittle of the law to fail” (Luke 16:17).
The Bible is clear that the law of God cannot be changed. The commandments are revealed principles of God’s holy character and are the very foundation of His kingdom. They will be true as long as God exists.
“My covenant I will not break, nor alter the word that has gone out of My lips” (Psalm 89:34).
“All His precepts [commandments] are sure. They stand fast forever and ever” (Psalm 111:7, 8).
We are told in the Bible that sin is the breaking of the law in 1 John 3:4. All throughout the Bible God's people and Jesus make it clear that we have to abide by God's law. Here is some scripture from the Bible to prove that.
“Happy is he who keeps the law” (Proverbs 29:18).
“Keep my commands; for length of days and long life and peace they will add to you” (Proverbs 3:1, 2).
“I would not have known sin except through the law. For I would not have known covetousness unless the law had said, ‘You shall not covet’ ” (Romans 7:7).
“He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him” (1 John 2:4).
“This is the love of God, that we keep His commandments. And His commandments are not burdensome” (1 John 5:3).
While Jesus was on earth He obeyed the law completely and He is our example according to the Bible. He did not abolish the law but fulfilled it. Instead of doing away with the law, Jesus magnified it. He said in Matthew 5:17-18, "Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled."
I won't say too much about the Sabbath because I have a forum on that, but the Sabbath is a requirement because its part of the ten commandments and while Jesus was on earth He obeyed it like all the other commandments. The Bible tells us in James 2:10, “Whoever shall keep the whole law, and yet stumble in one point, he is guilty of all” The Ten Commandment law guides us into holy living. If we ignore even one of the commandments, we neglect an essential part of the divine blueprint. If only one link of a chain is broken, its entire purpose is undone. The Bible says that when we knowingly break a command of God, we are sinning (James 4:17) because we have refused His will for us. Only those who do His will can enter the kingdom of heaven. Of course, God will forgive anyone who genuinely repents and accepts Christ’s power to change him or her.
Its important to mention that none of us can be saved by keeping the law. Ephesians 2:8-9 says, "By grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast” Romans 3:20 says, "By the deeds of the law no flesh will be justified in His sight” No one can be saved by keeping the law. Salvation comes only through grace, as a free gift of Jesus Christ, and we receive this gift by faith, not by our works. The law serves as a mirror that points out the sin in our lives. Just as a mirror can show you dirt on your face but cannot clean your face, so cleansing and forgiveness from that sin come only through Christ. Many think that doing good works guarantees their salvation even if they ignore keeping the law Hence, they think they are righteous and saved when, in fact, they are sinful and lost. “By this we know that we know Him, if we keep His commandments” (1 John 2:3).
Jesus also said, “If ye love me, keep my commandments” (John 14:15). Those who practice any known sin are really confessing that they do not love God with all their heart, soul, and mind. It goes without saying it is impossible for us to obey the law in our human power alone. “I can do all things through Christ which strengtheneth me” (Philippians 4:13).
Those who will make it to heaven and eternal life with be those who obey God's will. Revelation 14:12 says, “Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.”
Do you see why we'll all judged by the law?
