'Doing' in the Bible

eternal life to those who by persistence in doing good seek glory, honor, and immortality;

For I do not understand what I am doing, because I do not practice what I want to do, but I do what I hate.

So now I am no longer the one doing it, but it is sin living in me.

Now if I do what I do not want, I am no longer the one doing it, but it is the sin that lives in me.

ButIf your enemy is hungry, feed him.If he is thirsty, give him something to drink.For in so doingyou will be heaping fiery coals on his head.
