'Work' in the Bible

Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.

If any man's work abide which he hath built thereupon, he shall receive a reward.

If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.

Am I not an apostle? am I not free? have I not seen Jesus Christ our Lord? are not ye my work in the Lord?

Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord.

Now if Timotheus come, see that he may be with you without fear: for he worketh the work of the Lord, as I also do.
