Most of the grammar has been done by 2,000 years of scholarship so our best bet is to read the text and we won't be too far off:

Rom. 6:3 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
Rom. 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.
Rom. 6:5 For if we have been planted together in the LIKENESS of his death,
        we shall be also in the likeness of his resurrection:

We were not in the TOMB with Jesus but GRACE means that we can enact a PATTERN CAPABLE OF BEING IMITATED and God will credit us with the blood of Christ.

Rom. 6:6 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.
Rom. 6:7 For he that is dead is freed from sin.
 
WHEN WE OBEY THAT FORM OF DOCTRINE: A type meaning a pattern capable of being IMITATED.
.
Rom. 6:16 Know ye not, that to whom ye yield yourselves servants to obey,
        his servants ye are to whom ye obey;
        whether of sin unto death, or of obedience unto righteousness?
Rom. 6:17 But God be thanked,
        that ye were the servants of sin,
        but ye have obeyed from the heart that form of doctrine which was delivered you.

5179.  tupos, too´-pos; from 5180; a die (as struck), i.e. (by implication) a stamp or scar; by analogy, a shape, i.e. a statue, (figuratively) style or resemblance; specially, a sampler (“type”), i.e. a model (for imitation) or instance (for warning): 

Rom. 6:18 Being THEN made free from sin,
        ye became the servants of righteousness.

No one is born a sinner. They sin on their own. When they turn to Christ we can be REBORN in our spirit when God removes sin FROM OUT spirit so that WE have A holy spirit.

No one can be FREED from sin unless they are old enough to be aware and are able ON THEIR OWN to obey that which is commanded as the ARCHE Gospel or most important part for we who did not perform the PROTO gospel.

1Pet. 4:17 For the time is come that judgment
        must begin at the house of God: and if it first begin at us,
        what shall the end be of them that obey not the gospel of God?

You can obey GOSPEL or GOOD NEWS that your sins can be paid for without YOU having to die on the cross and then to no avail.  Wonder why the MASSES fight the very means God chose to TRANSMIT GRACE?

The fact is that the REMNANT will always be very tiny: invisible and inaudible to the watching world on Sunday.

Arise and be baptized and wash away thy sin calling on the name of the Lord. If you were sprinkled as an infant you are still in your sins because you have not enlisted as a DISCIPLE because only DISCIPLES are called CHRISTIANS and you did not become a DISCIPLE as a child. MOST religionism is ordained to PREVENT YOU from obeying such a simple act of REQUESTING A good conscience which is A holy spirit. DO IT.
