You didn't quote that becasue it doesn't say that.
Forgiving others is the first part of each of those passages. And it is suggested in the verses I showed which
actually state they are the foundation of all scripture.
Luke 6:31 Do to others as you would have them do to you.
Galatians 5:14 The entire Law is fulfilled in a single decree:
"Love your neighbor as yourself."
Romans 13:8 Be indebted to no one, except to one another
in love, for he who loves his neighbor has fulfilled the Law.
Matthew 7:12 In everything, then, do to others as you would
have them do to you.
For this is the essence of the Law and
the prophets.
Are you a Jew? The Law STATES IN BLACK AND WHITE that it is FOR the Hebrews - and ONLY for the Hebrews, nobody else. The Prophets refer to the Law, which is exclusively for the Hebrews, and instruct the Hebrews. And Jesus said that not a penstroke of the Law would change until the end of the world - MEANING that the Law of the Hebrews and FOR the Hebrews, exclusively, NEVER extended PAST the Hebrews - for that would be changing the Law, which Jesus said would never happen.
So, Jesus, speaking to Jews - just Jews - he didn't WRITE those words, he SPOKE them, in public, to Jews, just Jews, told them that the essence of THEIR Law and THEIR Prophets was "Love your neighbor as yourself and love God above all."
That's great.
Problem. I'm not a Jew. Which means that the Law and the Prophets never applied to me, in any sense, and never will. All of that Law of Moses, all of those Prophets urging those Hebrews to return to the Law of Moses - for me, these are not laws. Not a jot nor a tittle of that law ever applied to me, and Jesus says they never will.
So, for the Jew struggling to coordinate the revelations TO THE HEBREWS of Moses, and the revelations to the Jews of Jesus, what Jesus says is very important. THEY have to figure out how to take a massive ritual law, Ten Commandments that talk about a Sabbath, a "Chosen People", tribal lineage, all of that two thousand years of prior history, and see it through the lens of their Messiah.
But Jesus isn't the Messiah for ME - I'm not a Jew. That Law and those Prophets did not, and DO not apply to me. He isn't sacrificed on the altar to end MY need to sacrifice lambs on an altar - I'm not a Jew, and God never gave the law of animal sacrifice to me in the first place.
And Jesus said that the Jewish law could never be extended - at all - not a letter of it - past what was written. It SAYS it was for Hebrews only, and it remains for Hebrews, only, until the end of the earth.
So, what Jesus was saying to Jews, to deal with their Law and Prophets, is interesting to them.
It teaches me: Love your neighbor as yourself, and love God above all. But it doesn't drag in the Jewish Law and place me under it. Jesus says I can't EVER BE under it, because the Law can't change, and as written, I'm not under it.
So that is that.
For ME, a Gentile, what is important is following Jesus. I don't have to contend with the Law of Moses - it is totally utterly completely irrelevant to me and my line, from the beginning of time to the end of time.
What Jesus said about charity: that is Law for me.
What Jesus said the sins are: that is Law for me.
What Moses and the Prophets said? Relevant to the Jews to whom Jesus was speaking. Utterly irrelevant to me: God never placed me under that Law, and Jesus said that I'd never BE under it - for the law can never change. Out at the beginning, out until the end of the world.
The law that applies to ME is the list of things Jesus said to do, and in particular the things he said that will fail me final judgment.
Moses revealed a way for Hebrews to be freed from sin, through animal sacrifices, but I'm not a Hebrew, so my people never had those means available to free THEM from sin, and we still don't.
What, then, are we to do? What Jesus said: for God to forgive ME, I have to forgive others. If I forgive a little, I will be forgiven a little. For me to be forgiven everything, I have to forgive everything.
That's it. That's all.
I'm not Jewish, so I don't have to struggle with coordinating Jewish Law with Jesus. It didn't apply to me and still doesn't.
If you're Jewish, then I guess you do have to worry about The Law and the Prophets. I have studied them in depth. Truth is, you end up just having to follow Jesus anyway, but to feel ok about ignoring 90% of the Law as written means that you have to go through the exercise of understanding what the Law and Prophets are ABOUT, and what Jesus has to say there, and a great deal of Paul, is all about squaring that circle.
I wasn't in that circle to begin with, so I don't have to bother with worrying about it. And I don't.
So no, what Jesus says about The Law and the Prophets is not at all the most important thing. That only matters to Jews, nobody else. The rest of us never were under the Law, and those Prophets weren't addressed to us. We DO have to worry about what Jesus said is sin, and what we have to do to be forgiven it - and that is to forgive, just as Jesus said.
THAT is The Law for US.
If you're a Jew also, well, then you've got a lot longer row to hoe, and Jesus and Paul and John gave you very detailed instructions for working that all out.
