So Jesus said to the Jews who had believed in him, “If you abide in my word, you are truly my disciples, and you will know the truth, and the truth will set you free.” They answered him, “We are offspring of Abraham and have never been enslaved to anyone. How is it that you say, ‘You will become free’?”
Jesus answered them, “Truly, truly, I say to you, everyone who commits sin is a slave to sin. The slave does not remain in the house forever; the son remains forever. So if the Son sets you free, you will be free indeed. John 8:31-36
We know that our old self was crucified with him in order that the body of sin might be brought to nothing, so that we would no longer be enslaved to sin. For one who has died has been set free from sin…Let not sin therefore reign in your mortal bodies, to make you obey their passions…For sin will have no dominion over you, since you are not under law but under grace…Do you not know that if you present yourselves to anyone as obedient slaves, you are slaves of the one whom you obey, either of sin, which leads to death, or of obedience, which leads to righteousness? But thanks be to God, that you who were once slaves of sin have become obedient from the heart to the standard of teaching to which you were committed, and, having been set free from sin, have become slaves of righteousness…When you were slaves of sin, you were free in regard to righteousness. But what fruit were you getting at that time from the things of which you are now ashamed? The end of those things is death. But now that you have been set free from sin and have become slaves of God, the fruit you get leads to sanctification and its end, eternal life. For the wages of sin is death, but the free gift of God is eternal life in Jesus Christ our Lord.
Romans 6:6, 12, 14, 16-18, 20-23
For the law of the Spirit of life has set you free in Christ Jesus from the law of sin and death.
For freedom Christ has set us free; stand firm therefore, and do not submit again to a yoke of slavery…For you were called to freedom, brothers. Only do not use your freedom as an opportunity for the flesh, but through love serve one another. Galatians 5:1, 13
Live as people who are free, not using your freedom as a cover-up for evil, but living as servants of God. 1 Peter 2:16
Let it be known to you therefore, brothers, that through this man [Jesus] forgiveness of sins is proclaimed to you, and by him everyone who believes is freed from everything from which you could not be freed by the law of Moses. Acts 13:38
For whatever overcomes a person, to that he is enslaved. 2 Peter 2:19
When you buy a Hebrew slave, he shall serve six years, and in the seventh he shall go out free, for nothing…But if the slave plainly says, ‘I love my master, my wife, and my children; I will not go out free,’ then his master shall bring him to God, and he shall bring him to the door or the doorpost. And his master shall bore his ear through with an awl, and he shall be his slave forever. Exodus 21:2, 5-6
Paul, a servant (Gk, bondslave) of Christ Jesus, called to be an apostle, set apart for the gospel of God…Romans 1:1
Have this mind among yourselves, which is yours in Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped, but made himself nothing, taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross. Therefore God has highly exalted him and bestowed on him the name that is above every name, so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father. Philippians 2:5-11
Which one? Free? Or slave?
If I am a slave, then the question I must ask myself is, To which Master does my life demonstrate allegiance?
