Okay, I'll rephrase that: "The gods of the people are demons, but the Lord created the heavens." Well, I think now it's definitely "not a tale about the Gingerbread Man." Because there's context: their gods (who they worship) are demons, and our God (who we worship) is the creator of heaven (and everything else, of course). How can you conclude from this that it's about some kind of benefits? Everything is clear and precise. It's about comparing worship. Who do "the people" worship, and who do we worship? For pagans, the object of worship is not earthly benefits as such, but gods that embody various aspects of human life, elements, etc., that is, everything that is included in the concept of pagan cult. Yes, there are gods of wealth, power, good, and evil. This is what the psalm has in mind, and not moral worship of "passions." Don't turn David into a medieval scholastic theologian.
And how Christians understand this and other phrases from scripture can be seen from history. I think, no comment is needed.
In general, the Bible develops two opposite qualities in a person: I am sinful, but I am righteous. The question arises: so, am I sinful or righteous? If I am sinful, then stop sinning to be righteous. But no, I can't - original sin prevents me (we are already justifying ourselves), but I believe in the true and righteous God who created heaven and earth, and at the same time showed me that I am sinful. Well, if I can't help but sin, then at least I will be comforted by the promised reward in heaven and will weepingly repent of all the sins that I will still commit, because I cannot help but sin (original sin does not allow it). But I believe in the true and righteous God who created heaven and earth... and so on in a circle. In essence, it turns out to be a "tale about the Gingerbread Man."
And original sin does not prevent one from not sinning. Do you think the saints were born sinless? HA! Ha, and one more HA! Nikolai the Miracle-Worker, Seraphim of Sarov, and even the twelve apostles, they all had this original sin - and nothing! Now, they are watching over us from Paradise. And, believe it or not, they pray for us. And repentance is not forgiven if it is not sincere. The trick of "I will repent, and then I will start sinning again, then I will repent again and be clean" does not work here. Yes, there are people (and there are many of them) who still sin, but sin is like a drug: pleasant to the taste and you get incredibly addicted to it very quickly. Everyone, sooner or later, tries it, many struggle with their addiction, some overcome it. The rest, blaming themselves for their weakness of spirit, go to confession again, hoping that this time they will be able to defeat the demon within themselves. And they succeed! But only after many years, in old age, so that later they can be eternally young (or gray-haired again, depending on what a person likes more) and enjoy the blessings of Paradise. There is no tale about the Gingerbread Man here, don't blaspheme (Blasphemy is blasphemy against God).
