That is a denial of the Spirits work in romans 6:6....the old man was crucified...we do not have to keep crucifying him...it was complete.
This is not true.
Why did Paul say in 1Cor.15:31, "I die daily?"
Every day he put his body to death. He crucified himself every day.
Why did Jesus say: "If man shall come after me let him deny himself, take up his cross
daily and follow me.
Again, every day his disciples were to crucify themselves. It was daily.
The key to understanding the Scriptures is to understand that much of it is written in imagery. I am not suggesting we interpret it allegorically, far from it. But we need to recognize the metaphors, similes, and other imagery that is used.
Why a cross? The cross was the symbol for execution. Christ died on a cross as did two thieves. Every criminal was put to death that way. To take up one's cross was to die to the world, to die to self. OTOH, it was to submit to Christ. If I submit to him I will be dead to the world. Obviously death does not mean a literal death. It is used in a figurative sense. Most of the time "death" means separation. When I live for Christ I am separated from sin and the world. I must conscientiously do this every day.
In reference to Romans 6, as was previously mentioned, the entire chapter ought to be taken into context for a full understanding.
Verse 1 and 2 are an answer to the antinomianism expressed at the end of chapter five:
Romans 6:1 What shall we say then? Shall we continue in sin, that grace may abound?
2 God forbid. How shall we, that are dead to sin, live any longer therein?
--We will not continue in sin. Why? We are dead to sin. Dead to sin, how? We must make the conscious decision every day to be dead to sin. It would be wonderful if victory were so automatic, so complete that (being dead), I didn't have to do anything. Since I am automatically dead to sin (as you suggest), I ought to be sinless. But that is not true.
Verse 11--I reckon myself to be dead to sin. The word reckon infers something I must do. It is not automatic.
Romans 6:3 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
--Clearly this is the beginning of a picture of water baptism. The word baptism ALWAYS means "immerse." If we are united with Christ we are immersed into his death (a picture). "Into" means "in relation to" and speaks of the ordinance of water baptism.
Romans 6:4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
5 For if we have been planted together in the likeness of his death, we shall be also
in the likeness of
his resurrection:
Baptism has two pictures here:
The death, burial and resurrection of Jesus Christ.
As he died, so we died.
As he was buried, so we were buried (in water).
As he arose, so we arose (out of the water) [Hopefully the pastor didn't leave you under

]
When he died he took upon himself the burden of our sin, paid the penalty in full.
When we "died" we died in picture only, turning our back on the world and its sin, and our rebelliousness to God.
When he was buried, it was proof that he was dead.
When we were buried (in water) it is evidence that we indeed are dead to our old life in sin.
When he arose from the dead he conquered sin; he was victorious.
When we arose (from water), it was to a new life in Christ (symbolically--to what took place at salvation.).
Death means separation.
The wages of sin is death. The unsaved will be eternally separated from God.
When we die we separate ourselves from sin. It is a conscious effort to be made every day.
I like what Annsi said in another thread that really makes a practical application in this.
She said: When one of those Victoria Secret commercials comes on the TV my husband quickly turns to me, kisses me and says, "I love you." He doesn't want the temptation.
That is being dead to sin. It is the practice of it. It must be practiced every day. It does not come automatically. If it was you would be sinless.
You do have an old nature. You do struggle with it. We all do. It is not dead; it is very much alive.
