Paul and Timothy, servants of Christ Jesus,
To all the saints in Christ Jesus who are at Philippi, with the overseers and deacons: (ESV)
The Greek word translated "servants" in the ESV is douloi, meaning "slaves."
Slaves of Christ Jesus. His slaves. Some people think that the Bible doesn’t do enough to speak out against slavery. Some people think that the Bible sanctions slavery. In one sense it absolutely promotes slavery, the slavery of men and women to Jesus Christ.
Happy are those who are slaves to Christ. Blessed are the slaves of Christ. There is no one else more happy or blessed than those who obey Jesus Christ fully.
Were it truly inscribed on my tombstone the simple statement, “He was a slave of Christ Jesus,” the passerby could know at least two things: that Christ’s Spirit had thoroughly claimed me, and that I had achieved true happiness, a whatever-my-earthly-circumstances joy.
