'Works' in the Bible

They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate.

In all things shewing thyself a pattern of good works: in doctrine shewing uncorruptness, gravity, sincerity,

Who gave himself for us, that he might redeem us from all iniquity, and purify unto himself a peculiar people, zealous of good works.

Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;

This is a faithful saying, and these things I will that thou affirm constantly, that they which have believed in God might be careful to maintain good works. These things are good and profitable unto men.

And let ours also learn to maintain good works for necessary uses, that they be not unfruitful.
