Romans 6:5-7 // Freedom from Sin (?)

For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection: 6 Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin. 7 For he that is dead is freed from sin. (Romans 6:5-7)

Thy people also shall be all righteous: they shall inherit the land for ever, the branch of my planting, the work of my hands, that I may be glorified. (Isaiah 60:21)

This seems to be a bit of a repetition or reiteration of the previous verses, but there is more to see. So we  have already established that by being baptised we symbolically died with Christ on the cross so when we were raised out of the water it symbolised the new life that Christ has given us.
Isaiah 60:21 refers to the people of God as something God has planted. I think the reference in Romans is to being buried, the same way a plant is buried when it is planted, but I think this parallel is still worth noting. So Jesus was planted and I was planted with him. Jesus sprang to life and I sprang to life with him.
Sometimes people talk about our sinful body being destroyed and replaced with a sinless body when Jesus returns. But here the Bible teaches that at the point of conversion our body is, in some profound way, destroyed and so from the point of conversion we are no longer slaves to sin.
When I work for a man I must do what he says, but I can choose to leave and never come back. When a slave works for a man he does similar things but he can never choose to quit, he is a slave. When a slave is freed he may choose to continue working for his old master. When Jesus frees us from slavery to sin, we continue to work for Satan because that is what we are used to doing, but we do not need to do this. As the physically dead man is beyond the reach of temptation or retribution, the converted follower of Christ is beyond the reach of any temptation too strong for him to bear and is also saved from divine punishment.
If you are saved you are not a slave, you can choose to stop serving sin. When I was a child I was a slave to my temper. I would sometimes lose it and could be quite scary, but even when I didn't lose it I simmered with anger, I was quick to resent things. When I confessed it to Christ and asked him to change me, he changed me literally over night. But since then there have been times that I have gone back to this, not as a slave, but a willing participant. The work that the Holy Spirit has been doing in me has been to remove the desire to be angry and aggressive, this has taken a lot of time.

Freedom from the slavery to sin, freedom to choose right and shun (stay away from) wrong is mine and yours the moment we give all to Jesus. To no longer have the taste for sin takes longer, perhaps a lifetime.
