Nor with eye-service - That is, not with service rendered only under the eye of the master, or when his eye is fixed on you. The apostle has here adverted to one of the evils of involuntary servitude as it exists everywhere. It is, that the slave will usually obey only when the eye of the master is upon him. The freeman who agrees to labor for stipulated wages may be trusted when the master is out of sight; but not the slave. Hence the necessity where there are slaves of having "drivers" who shall attend them, and who shall compel them to work. This evil it is impossible to avoid, except where true religion prevails - and the extensive prevalence of true religion would set the slave at liberty. Yet as long as the relation exists, the apostle would enjoin on the servant the duty of performing his work conscientiously, as rendering service to the Lord. This direction, moreover, is one of great importance to all who are employed in the service of others. They are bound to perform their duty with as much fidelity as though the eye of the employer was always upon them, remembering that though the eye of man may be turned away, that of God never is.
As men-pleasers - As if it were the main object to please people. The object should be rather to please and honor God.
But as the servants of Christ - see the notes on 1-Corinthians 7:22.
Doing the will of God from the heart - That is, God requires industry, fidelity, conscientiousness, submission, and obedience in that rank of life. We render acceptable service to God when, from regard to his will, we perform the services which are demanded of us in the situation in life where we may be placed, however humble that may be.

Not with eye-service - Not merely in their presence, when their eye is upon you, as unfaithful and hypocritical servants do, without consulting conscience in any part of their work.
Doing the will of God - Seeing that you are in the state of servitude, it is the will of God that you should act conscientiously in it.

Not with eyeservice, as menpleasers; but as the servants of Christ, (9) doing the will of God from the heart;
(9) To cut off occasion of all pretences, he teaches us that it is God's will that some are either born or made servants, and therefore they must respect God's will although their service is ever so hard.

Not with eyeservice, as menpleasers,.... Doing nothing but when under the master's eye, and then pretending a great deal of diligence and industry, in order to ingratiate themselves into his affections, and neglecting his business when he is absent; whereas they ought to attend his service in his absence, as well as in his presence, and so seek to please him, which is commendable.
But as the servants of Christ; acting in like manner as the servants of Christ, who are not menpleasers; or as if they themselves were serving Christ, as indeed they are, when they are doing that which is the will of Christ:
doing the will of God from the heart; meaning not the will of God in a religious, but in a civil sense, yielding a cheerful and hearty obedience to their own masters.

(Colossians 3:22). Seeking to please their masters only so long as these have their eyes on them: as Gehazi was a very different man in his master's presence from what he was in his absence (2Ki. 5:1-18).
men-pleasers--not Christ-pleasers (compare Galatians 1:10; 1-Thessalonians 2:4).
doing the will of God--the unseen but ever present Master: the best guarantee for your serving faithfully your earthly master alike when present and when absent.
from the heart--literally, soul (Psalm 111:1; Romans 13:5).

Not with eye - service - Serving them better when under their eye than at other times. But doing the will of God from the heart - Doing whatever you do, as the will of God, and with your might.
