Matthew Henry Commentary Titus 2:9-10

"[Exhort] servants to be in subjection to their own masters, [and] to be well-pleasing [to them] in all things; not gainsaying; not purloining, but showing all good fidelity; that they may adorn the doctrine of God our Saviour in all things." — Titus 2:9-10 (ASV)

Servants must know and do their duty to their earthly masters, with reference to their heavenly Master. In serving an earthly master according to Christ's will, Christ is served; those who do so will be rewarded by Him.

They should not use disrespectful or provoking language, but rather accept a rebuke or reproof with silence, not offering defiant or overconfident replies. When conscious of a fault, excusing or justifying it only doubles the offense.

They should never put to their own use what belongs to their master, nor waste the goods with which they are entrusted. Furthermore, they should show all good fidelity to improve a master's goods and promote his prosperity.

As Scripture says, If you have not been faithful in that which is another man's, who will give you that which is your own? (Luke 16:12). True religion is an honor to those who profess it, and they should adorn it in all things.
