'Doing' in the Bible

Therefore you are without excuse, O man, every one [of you] who passes judgment. For in that which you pass judgment on someone else, you condemn yourself, for you who are passing judgment are doing the same [things].

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

But now I am no longer the one doing it, but sin that lives in me.

For I know that good does not live in me, that is, in my flesh. For the willing is present in me, but the doing [of] the good [is] not.

But if what I do not want [to do], this I am doing, I am no longer the one doing it, but sin that lives in me.

But "if your enemy is hungry, feed him; if he is thirsty, give him [something] to drink; for [by] doing this, you will heap up coals of fire upon his head."
