'Work' in the Bible

Therefore, if anyone cleanses himself from these things [which are dishonorable—disobedient, sinful], he will be a vessel for honor, sanctified [set apart for a special purpose and], useful to the Master, prepared for every good work.

so that the man of God may be complete and proficient, outfitted and thoroughly equipped for every good work.

But as for you, be clear-headed in every situation [stay calm and cool and steady], endure every hardship [without flinching], do the work of an evangelist, fulfill [the duties of] your ministry.
