The New Testament has one other general word for sin, which is hamartema, a word used a total of four times. The first is found in Mark 3:28, where Jesus says that all sins shall be forgiven the sons of men, along with their blasphemies. He goes on to say that blasphemy against the Holy Spirit will not be forgiven. And then, in the next chapter (4:12), He gives an example of the kind of spiritual darkening that the light of the parables causes. If the deaf heard, and the blind saw, then they would be converted and their sins forgiven them. But they can’t and don’t, and their sins remain.
Paul mentions that Christ’s blood is a propitiation for those who have faith, and that this declares His righteousness for the remission of past sins (Rom. 3:25). And in his letter to the Corinthians (1 Cor. 6:18), Paul tells them to flee from fornication because it is a sin that is not, like others, outside the body. Fornication defiles the temple of the body in the way that other sins do not. It is worth noting here that Paul expressly excludes “sins” against the temple like smoking or eating too much refined sugar. This is not a passage that is talking about staying fit — it is a passage about staying sexually moral, and expressly limits the scope of discussion to only that.
