Failure. The concept put forward here is the temple and the law failed. But they actually succeeded in demonstrating the problem of sin and the path to reconciliation. A few through faith found the place of intimacy with God, Moses, the prophets, David etc. but they were few, and what was demonstrated was confusion and failure to understand.
Jesus took all the violence, hatred, bitterness that people could throw at Him and forgave them unto death. The judge said if you follow me, I will not hold your sin against you. The key is to aim at holiness, empowered by the Spirit. But this is the inheritence of the law and the prophets not a new gospel. And the sin not held against us is sin done in ignorance, not will full. And the condition is on following.
Everything in hyper-grace sounds ok except not repenting of sin, changing the temple etc in failure and not a shadow, and making the gospel about compromise and not righteousness. The sin we do is our sin, and we need to understand it, in intimate detail, so we can overcome it, and be set free. Jesus carried the consequences of sin, death, and forgave us.
We are saved because we admit the sins commited against Jesus are our sins, so we are forgiven, or the punishment is not taken on us for them. Unless we follow then this is no longer true. We put Jesus to death, we need to drink His blood and eat His flesh, to know the depths of love He has for us.
But the sin is ours not Jesus's. We need to be honest about it, and work through it, not ignore it, and say it belongs to someone else. That is called denial, projecting on to another bad behaviour that we ourselves do. In psychological terms this leads to the worst types of behaviour and disfunctional outlooks. Jesus calls us to own our sin, admit it and turn from it. It is humbling, difficult and painful. It deals with the excuses, the pain inflicted upon others and how we are guilty.
But in the end Jesus says, "I forgive you, sin no more."
