Slave, Servant, Bond-Servant, and Sin: Who Is My Master?
Slave, Servant, Bond-Servant, and Sin: Who Is My Master?
My recent studies have led me into a deep question: Is sin something I choose, or something that controls me? Am I a slave to sin? A slave to Satan? Or does Satan simply take advantage of my slavery to sin?
The Bible is clear that all people, by nature, are slaves to sin; we have lost our self-control. As Jesus said, “Truly, truly, I say to you, everyone who commits sin is the slave of sin.” (John 8:34) If that is true, then another question follows: does being a slave to sin mean I am also a slave to Satan? Satan is called “the ruler of the world” (John 12:31) and “the god of this age” (2 Corinthians 4:4). We all begin life as part of this world, so if Christ is not my master, could it be that Satan is?
Slave vs. Servant: What’s the Difference?
In English, “slave” sounds harsh and “servant” sounds gentler. But in the New Testament, the Greek word behind both is usually the same: doulos. Sometimes it is translated “slave,” sometimes “servant,” depending on the Bible version. I personally prefer translations that use both, because they help show the range of meaning.
Our dictionaries reflect this overlap. A slave can be “a person who has lost self-control and is controlled by something or someone else,” while a servant is “one that serves others.” A bond-servant is “one bound to service without wages; also: slave.” These two English words, slave and servant, are really the same; it is just a way to show different degrees of harshness or kindness between a person and their master.
A master lays out what a slave’s responsibilities are and the punishments for disobedience. When we call someone a slave, the degree of harshness on that slave by their master is at its worst. As I once wrote, “Punishments are carried out to the letter and at times even when they are undeserved. The master does whatever he wants to that slave and the slave is forced to obey. This is Satan's way.”
I tend to see a servant as being in a better place or condition than a slave, but the more I think about it, it all boils down to the relationship between a slave or servant and his or her master.
God as Master and the Master Who Paid Our Penalty
God is the creator of everything and everyone, including the heavenly creatures. He is the master of all and, by rights, we are His servants—His slaves. God has given us His laws and the punishment for disobedience, which is death. Yet here is the wonder of the gospel: “What master has ever paid the punishment himself for his servant.” God has done this through His Son, Jesus.
We all are disobedient, worthy of death, and Jesus has died in our place. On the third day He arose from the dead and now He sits at the right hand of the Father. Jesus is not just sitting there; Father God has made Jesus Master, and He is the best Master anyone could ever dream of having. He works with us in the work He gives us to do—if we will accept Him as Master.
Jesus Himself invites us:
“Come to Me, all who are weary and heavy-laden, and I will give you rest. Take My yoke upon you and learn from Me, for I am gentle and humble in heart, and you will find rest for your souls. For My yoke is easy and My burden is light.” (Matthew 11:28–30)
He also says:
“No longer do I call you slaves, for the slave does not know what his master is doing; but I have called you friends, for all things that I have heard from My Father I have made known to you.” (John 15:15)
From Slavery to Adoption and Freedom
Romans 8 gives us a powerful picture of what God has done for us in Christ. We were under the law of sin and death, unable to truly obey God. Our minds set on the flesh led to death, hostility toward God, and slavery to corruption.
But in Christ Jesus, “the law of the Spirit of life has set you free from the law of sin and of death.” We are no longer condemned if we are in Christ. God sent His own Son “in the likeness of sinful flesh and as an offering for sin,” so that the requirement of the Law might be fulfilled in us who walk according to the Spirit.
Paul writes that we “have not received a spirit of slavery leading to fear again, but… a spirit of adoption as sons by which we cry out, ‘Abba! Father!’” The Spirit Himself testifies with our spirit that we are children of God, and if children, then heirs—heirs of God and fellow heirs with Christ.
Creation itself is waiting to be “set free from its slavery to corruption into the freedom of the glory of the children of God.” We groan, we wait, but we do so in hope, knowing that nothing “will be able to separate us from the love of God, which is in Christ Jesus our Lord.”
So Who Is My Master?
The real question is not whether we serve a master, but which master we serve. Without Christ, we are slaves to sin. Satan, the ruler of this world and the god of this age, takes advantage of that slavery. We are owned by what controls us.
With Christ as our Master, everything changes. His yoke is easy, His burden is light, His heart is gentle and humble. He calls us friends. He gives us His Spirit. He adopts us as sons and daughters. He makes us heirs. And He promises that nothing in all creation can separate us from His love.
We may still suffer, but “in all these things we overwhelmingly conquer through Him who loved us.” Our slavery to sin is replaced by loving service to a good Master, and our fear is replaced by the freedom of being children of God.
Closing Reflection and Prayer
As I think about slave, servant, and bond-servant, I see more clearly that my life will always be lived under some kind of mastery. Either sin and Satan will rule me, or Christ will. The difference is not just in the word used, but in the heart of the One who holds my life. In Jesus, the Master Himself has borne my punishment, called me His friend, and welcomed me as His child.
Prayer:
Father God, thank You that You did not leave me as a slave to sin and fear. Thank You for sending Jesus to bear the punishment I deserved and to break the power of sin and death. Lord Jesus, I confess You as my Master, my Savior, and my Friend. Teach me to walk by Your Spirit, to serve You with a willing heart, and to rest in Your gentle yoke. Holy Spirit, remind me daily that I am a child of God—adopted, loved, and secure—and that nothing in all creation can separate me from the love of Christ. In Jesus’ name, amen.
