'Work' in the Bible

And I went up by revelation; and I put before them the good news which I was preaching among the Gentiles, but privately before those who were of good name, so that the work which I was or had been doing might not be without effect.

But let every man make test of his work, and then will his cause for glory be in himself only, and not in his neighbour.

Because every man is responsible for his part of the work.
