'Work' in the Bible

who shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts accusing or else excusing themselves between themselves;)

but to him who does not work, but believes on him who justifies the ungodly, his faith is reckoned as righteousness.

But we do know that all things work together for good to those who love God, to those who are called according to purpose.

For rulers are not a terror to a good work, but to an evil one. Dost thou desire then not to be afraid of the authority? practise what is good, and thou shalt have praise from it;

For the sake of meat do not destroy the work of God. All things indeed are pure; but it is evil to that man who eats while stumbling in doing so.
