Paul had been comparing the death and resurrection of Yeshua to what believers experience through faith as symbolized in baptism. He further explained in this next section.
Romans 6:5-11 (KJV)
For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
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.
For he that is dead is freed from sin.
Now if we be dead with Christ, we believe that we shall also live with him:
Knowing that Christ being raised from the dead dieth no more; death hath no more dominion over him.
For in that he died, he died unto sin once: but in that he liveth, he liveth unto God.
Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord.
Paul began in verse 5 by saying that believers are "planted." This is reminiscent of John's discussion in John 12.
John 12:24 (KJV)
Verily, verily, I say unto you, Except a corn of wheat fall into the ground and die, it abideth alone: but if it die, it bringeth forth much fruit.
Yeshua was like that seed of wheat that is planted in the ground (a kind of dying), that would bring forth much fruit. Believers are similarly planted with Yeshua in His death and they will also experience a similar resurrection.
Because believers have been crucified with Yeshua, their bodies of sin are destroyed (verse 6). Henceforth, believers should not serve sin.
Paul introduced a couple of terms in this verse that need clarifying. The "old man" is the entity that is crucified. "The old man was the natural man, the Adam man, earthy, natural, carnal, dead in personal trespasses, weak through the flesh, and could not please God" (Pearl, Michael. Romans 1-8, Verse by Verse. No Greater Joy, Pleasantville, TN, 200l. p. 112). This "old man" is now gone and is replaced by the "new man" in believers.
When the "old man" is crucified, the "body of sin" is also destroyed. The "body of sin" is "the physical body with all of its natural and accumulated lusts, tainted and depraved by a life of disobedience." (Pearl 113). Because the "old man" and the "body of sin" are gone believers should no longer sin.
According to verse 7 believers are virtually dead and are freed from sin.
Next, Paul turned to the subject of resurrection. If believers are dead with Yeshua, they are also alive with Him (verse 8). Because Yeshua was raised from the dead, He cannot die again. Death has no dominion over Him (verse 9). He died to sin once (verse 10). Now He lives unto God.
Paul then concluded that believers are to consider themselves dead to sin, but alive unto God through Yeshua (verse 11).
The burden of sin that surrounds us in our human state is removed by Yeshua, our Messiah, when we trust in Him! We are freed! Hallelu-Yah!
