1 Timothy 6:1-2 is not an endorsement of slavery, but it is an acknowledgment that slavery was part of the societal reality in which the church in Ephesus lived. Recognizing these realities, Paul instructs the church to live according to who they are in Christ, even in the brokenness of this world. In these verses, the Bible instructs Christians on how to labor for unbelieving masters and for masters who are fellow brothers in Christ.
