Romans 6 talks about our real, spiritual union with Jesus.  It’s about how God sees our position and status before Him.  He not only relates with us based on Jesus’ righteousness, but He frees us from sin’s power and penalty because when Christ died, our old sinful self died with Him, and when Jesus was raised from the dead, our new man was raised with Him.  Sin’s power no longer enslaves, and sin’s penalty no longer hangs over our heads.  That’s what this text is really about.
