Why Slaves of Righteousness?

Why did I name this blog after Romans 6:18?

The Bible is a book that bears repeat reading. On one such reading Romans 6:18 jumped right out at me. -"...and having been freed from sin, you became slaves of righteousness." (NASB)

Wow. I checked out the context.
Romans 6

Here we have Paul asking the Romans why they act as if they are still slaves to sin. They (and all Christians) have been freed from bondage to sin, why go back willingly?

Instead we are slaves of Righteousness-Christ's righteousness. So let's act that way.
It is not an oppressive slavery, but one of freedom in Christ. This theme reverberates throughout Romans 6 and elsewhere-such as Romans 7:6 and John 8:32. Martin Luther understood this and declared himself captive to God and His Word.

Yet, when we sin, we place ourselves back under sin's bondage. Yes, God forgives His people, and we rejoice in that. We are not to presume upon God though, we are to act in accordance with what we profess to believe. Before we believed we were slaves to sin, but we are freed.

Why do I repeat myself in this? It is very important for Christians to keep this in mind.
It was not our own power that freed us from sin, and it is not our own righteousness we are to be slaves to. It is the work of the Triune God-Father, Son & Holy Spirit. Why go back to what was?

Who or what is your Master? Whose slave are you?
