Romans 6:15

What then? shall we sin, because we are not under the law, but under grace? God forbid.
13

Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God, as those that are alive from the dead, and your members as instruments of righteousness unto God.

14

For sin shall not have dominion over you: for ye are not under the law, but under grace.

15

What then? shall we sin, because we are not under the law, but under grace? God forbid.

16

Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?

17

But God be thanked, that ye were the servants of sin, but ye have obeyed from the heart that form of doctrine which was delivered you.

Counter-Arguments

The strongest case that this verse does not belong in this theme.

Sabbath Fulfilled or Changed

The verse discusses being "under the law" versus "under grace" in the context of sin, but it does not specifically mention the Sabbath or any other particular law. Therefore, it does not directly support the idea that the Sabbath is fulfilled or changed.
