We do good deeds, not merely because the law requires us to, but because we are internally prompted to do them because we know and understand that it is good and right to do so, and because we know and understand that being faithful to God by loving God and serving the neighbor is the right way to live.
Under the old covenant, the ancient Jews showed their faithfulness primarily by behavioral obedience to a code of laws given for their culture by God. It didn't matter so much why they did so, as long as they did so. They were "kinesthetically" religious, meaning that their religion was primarily in their actions and their behavior.
That was not going to be how the new covenant made by Jesus Christ with his people would be. It would not be mere behavioral obedience to law. It would be an inner spiritual life and dictate called "faith" or "belief" that would guide us to follow the "law of faith," meaning laws critical to loving God and loving the neighbor, by a freely made internal assent to following God's ways in our life.
If we don't understand the overarching paradigm shift as a framework in which Paul's letters were written, then we fall prey to what Peter described:
> So also our beloved brother Paul wrote to you according to the wisdom given him, speaking of this as he does in all his letters. There are some things in them hard to understand, which the ignorant and unstable twist to their own destruction, as they do the other writings. You therefore, beloved, since you are forewarned, beware that you are not carried away with the error of the lawless and lose your own stability. (2 Peter 3:15-17)
And Paul, too, was at pains to say that he was not nullifying the law, but upholding it, yet through faith, or faithfulness, of the kind I just described:
> Do we then overthrow the law by this faith? By no means! On the contrary, we uphold the law. (Romans 3:31)
It's not that Christians are no longer required to obey any laws. It's not that Christians are no longer required to obey the Ten Commandments. Rather, our reason for obeying the law is different than under the old covenant. We no longer obey them due to simple obedience, but because we are now "in Christ," meaning we obey them for internal reasons.
And those laws of ritual and sacrifice that were given for the older, non-spiritual, flesh-oriented culture of the ancient Jews were no longer necessary because we have passed from behavioral obedience to living a spiritual life of loving God and the neighbor from an internal dictate and faithfulness to the spirit of the law.
And there is one further step. From the old covenant of external obedience to law we pass, in Christianity, to the new covenant of being guided by the spirit and light of Christ within us, so that we act from understanding, belief, and faithfulness in the fullest sense of those words. And from there we progress to acting not from faith first, but from love, as Paul says:
> Owe no one anything, except to love one another; for the one who loves another has fulfilled the law. The commandments, “You shall not commit adultery; You shall not murder; You shall not steal; You shall not covet”; and any other commandment, are summed up in this word, “Love your neighbor as yourself.” Love does no wrong to a neighbor; therefore, love is the fulfilling of the law. (Romans 13:10)
> For the whole law is summed up in a single commandment, “You shall love your neighbor as yourself.” (Galatians 5:14)
So we progress from obedience through understanding to love as the center and foundation of our covenant with God. Paul was shepherding the shift from obedience to understanding, which he called "faith." Now I believe we are making the transition that Paul and the other Bible writers predicted, from understanding to love.
@Joshua Good catch on Acts 2:29-36. Still, the point remains that the Bible doesn't say that David is in heaven. Meanwhile, the Bible does mention others going to or being in heaven, such as the thief on the cross, Abraham and Lazarus, and presumably Moses and Elijah as seen with Christ at the time of the Transfiguration.
@Joshua It's a fair question. And of course, we must all make up our own minds what we will believe, and how we will read the scriptures.
@Joshua However, I am not as skeptical as you are of our ability to read and understand the plain words of scripture, at least on the critical issue of our eternal salvation, without an interpretive lens. I believe that the Scriptures are actually quite clear on this critical issue.
@Joshua And the basic answer to your question is disarmingly simple: The Bible doesn't speak plainly of the fundamental Protestant doctrines of salvation, whereas it does speak plainly of the fundamental doctrine of salvation explained by Swedenborg.
@PaulVargas Circumcision is not a requirement among Swedenborgians. It's largely left to prevailing cultural and medical practices. My own belief is that it's unnecessary religiously or medically. I don't think God made a mistake in creating the human body the way it is, and I don't think it's necessary for us to remove part of it.
