Thoroughness is carrying out each task in preparation for God’s personal inspection and approval.
When David prayed, “Wash me throughly from mine iniquity, and cleanse me from my sin,” he used the Hebrew word “rabah,” which occurs 74 other times in Scripture as multiply. He was asking God to cleanse him over and over so that there would be no trace of sin or iniquity left. Thoroughness in cleaning is not accomplished by a “quick onceover” but by a deep cleaning and complete washing to make sure every bit of dirt or uncleanness is removed.
— Thoroughness in Work
We have a tendency to do work as thoroughly as is necessary to pass the inspection of those who assign us the job. However, true thoroughness is motivated by the awareness that each job we do will be personally inspected by the Lord. This is the message of Colossians 3:22–24: “Servants, obey in all things your masters according to the flesh; not with eyeservice, as menpleasers; but in singleness of heart, fearing God: And whatsoever ye do, do it heartily, as to the Lord, and not unto men; Knowing that of the Lord ye shall receive the reward of the inheritance: for ye serve the Lord Christ.”
