1TI 6:2

2 [Slaves] who have masters who believe [in Christ] must not be disrespectful to their masters just because their masters are fellow believers. Instead, they should serve [their masters] even better because [their masters] are fellow believers whom [God] loves and who benefit when [the slaves] serve them well. As you teach these things [to your congregation], exhort/urge [people] that they do them.
