Not with eyeservice, as menpleasers; but as the servants of Christ, doing the will of God from the heart;
Note 3 at Eph 6:6: Eph 6:5-8 instructs servants, which would be comparable to us as employees today (see note 1 at Eph 6:5), to serve their employers genuinely from the heart. We should not only do what's right or expected when our bosses are watching, but also do just as well when no one is watching. Failure to do so means we are man-pleasers. Our work should be unto Christ and not unto man (Eph 6:7). Those who have two standards, or two speeds of work (one for when they are being watched and one for other times), are liars and thieves. They are stealing from their employers and intentionally giving a false impression.
Note 4 at Eph 6:6: Notice that serving our employers (see note 1 at Eph 6:5) is called "doing the will of God." It is true that the Lord will show us overall goals and direction for our lives, but doing a good job for our bosses is also the will of God. There are thousands of everyday, practical ways that we fulfill the will of God in our relationships and actions. It would seem logical that until we begin to fulfill God's will in these small yet important ways, there is no point in the Lord showing us His long-term will (Lu 16:10-12).
