Romans 7:6 - To Love And Obey Is The Only Way

But now we are delivered from the law, that being dead wherein we were held;
that we should serve in newness of spirit, and not in the oldness of the
letter. Rom 7:6 (KJV)

But now, by dying to what once bound us, we have been released from the law
so that we serve in the new way of the Spirit, and not in the old way of the
written code. Rom 7:6 (NIV)

But now we're delivered from seeing the requirements of the law as a means
of salvation, because we're dead to the idea that salvation can be gained by
works.  We are no longer slaves to what we can do to earn salvation.  On the
contrary, we serve God willingly and joyously with a new life in the Holy
Spirit, not in the old way of the written code. Rom 7:6 (CWB)

Believers who have died to sin and risen to newness of life (ch. 6:2, 4) now
render a service that is new and spiritual. Their obedience to God's law is
no longer legalistic and mechanical, as if righteousness consisted merely of
compliance with a set of external rules of conduct, without any reference to
the condition of the heart. Through union with the risen Saviour believers
have learned a new way of true, heartfelt, spiritual obedience. Such service
and worship is possible only to those who have been born again of the Holy
Spirit and live under His influence. . . henceforth the believer no longer
serves God from a sense of legal bondage and fear, but in a new spirit of
freedom and love. [SDA Commentary]

This passage does not suggest that Christians have no obligation to obey
God. Actually, our obligations are now greater since we know Christ and
belong to God's family. The demands now are far more severe than under the
Mosaic law. For example, the Sermon on the Mount goes beyond outward actions
to deal with inward attitudes. The law of Moses found murderers guilty, but
Jesus said that hatred is equivalent to murder. But this passage teaches
that our motivation for obeying is different: we do not mechanically obey a
set of rules, but we lovingly, from the heart, obey the Spirit of God who
fulfills the righteousness of the Law in us (8:4). A beginning pianist can
play a number "letter perfect" and still not capture the inner spirit of the
song the way an accomplished musician can. Our obedience to God is not that
of a slave fearing a master, but that of a bride lovingly pleasing her
bridegroom. [Wiersbe Expository Outlines]

We serve in a new spirit, not in the old letter. Or better, in newness of
Spirit in contrast to the old legal code. In place of a legalism that
enforces statutes, there is a spirit of love and dedication. [Wycliffe Bible
Commentary]

Only a person who is spiritually alive can bear spiritual fruit, that is,
holy living (cf. John 15:4-5). A person who is married to Christ can bear
spiritual progeny. [Bible Knowledge Commentary]
