'Workmanship' in the Bible

the workmanship of each person will become evident, for the day of judgment will show what it is, because it will be revealed with fire, and the fire will test the quality of each person's action.

Am I not free [unrestrained and exempt from any obligation]? Am I not an apostle? Have I not seen Jesus our [risen] Lord [in person]? Are you not [the result and proof of] my work in the Lord?
