What shall we say then? Are we to continue in sin that grace may abound? (6.1) What then? Are we to sin because we are not under law but under grace?  (6.15a)

All authority in heaven and on earth has been given to me.

By no means! How can we who died to sin still live in it? (6.2) By no means! Do you not know that if you present yourselves to anyone as obedient slaves, you are slaves of the one whom you obey, either of sin, which leads to death, or of obedience, which leads to righteousness? (6.15b, 16)

Go therefore and make disciples of all nations

Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? (6.3ff)

by baptizing them in the name of the Father and of the Son and of the Holy Spirit

But thanks be to God, that you who were once slaves of sin have become obedient from the heart to the standard of teaching to which you were committed… (6.17ff)

by teaching them to observe all that I have commanded you.

(Note, I have said that I don’t think 6.1 has been understood.  I should note that by 6.15 we do seem in more “traditional” territory.)
