'Works' in the Bible

What doth it profit, my brethren, if a man say he hath faith, but have not works? can that faith save him?

Even so faith, if it have not works, is dead in itself.

Yea, a man will say, Thou hast faith, and I have works: show me thy faith apart from thy works, and I by my works will show thee my faith.

But wilt thou know, O vain man, that faith apart from works is barren?

Was not Abraham our father justified by works, in that he offered up Isaac his son upon the altar?

Thou seest that faith wrought with his works, and by works was faith made perfect;

Ye see that by works a man is justified, and not only by faith.

And in like manner was not also Rahab the harlot justified by works, in that she received the messengers, and sent them out another way?

For as the body apart from the spirit is dead, even so faith apart from works is dead.

Who is wise and understanding among you? let him show by his good life his works in meekness of wisdom.
