¹⁷ The sinful nature wants to do evil, which is just the opposite of what the Spirit wants. And the Spirit gives us desires that are the opposite of what the sinful nature desires. These two forces are constantly fighting each other, so you are not free to carry out your good intentions.

So they can’t keep on sinning, because they are children of God. ¹⁰ So now we can tell who are children of God and who are children of the devil. Anyone who does not live righteously and does not love other believers^[b] does not belong to God.
