Actually, Polycarp, I think I agree with you on all this. The law, as a covenant, is fulfilled and no longer binding - AS A WAY TO SALVATION AND TO GOD. However, that doesn’t change the fact that there is moral behavior that God wants, and sinful behaior that God does not want. The fact that we are not living under the law does not free us from God’s demand to strive for perfection or the fact that he cannot tolerate sin.
The forgiveness of Jesus does not free us to do just whatever - there is still behavior that is sinful. In addition to the most important two commandments (To love God with all your heart, soul, mind, and strength, Loving your neighbor as yourself), one of the first meetings of elders established four additional points under the Law that Christian believers must adhere to: Do not eat meat from strangled animals, do not eat blood, do not eat meat sacrificed to idols, and avoid sexual immorality.
As we both know, the law serves to show us our sinfulness; to show us that it is not possible for us to win God’s approval through good behavior. The law also profided a temporary fix - a bandage on a wound - to allow people, through God’s grace, to partake in Jesus’s salvation before it was completed, through the system of sacrifice (without the shedding of blood there is no remission of sin), which, as detailed in Hebrews, is just a shadow, a copy, a precursor to the REAL sacrifice that Jesus made. The sacrifices under the law covered sin, but the sacrifice of Jesus, the lamb of God, cleansed it (kind of like those commercials for Febreze: Other sprays just cover up odors. Febreze takes them away!).
But forgiveness does not excuse immoral behavior (What shall we say then? Shall we continue in sin, that grace may abound? - Romans 6:1). In fact, willfully continuing in sin makes a mockery of forgiveness. We will always continue to falter, of course (and smart alecks like Libertarian saying “Oh, have you sacrificed your lamb today?” are no help at all. Unless you think it’s amusing to cause your brother or sister to falter), but the great thing is that Jesus’s death paid for our future sin, as well as our past and present sin.
Love is the basis of salvation, but we are required to behave morally as well. And you can’t take certain statements, like “God is love” and take them so literally (and I think it’s ironic that some people are so entertained by mocking people like Jerseydiamond and His4ever as literalists, when they base their entire worldviews on an absolutely literal interpretation of that one statement) that you end up living by the reverse, Love is God, and worshipping Love itself.
