By in the flesh
Paul refers to
the unbeliever who is not in Christ; or
a determining condition that makes one susceptible to sin.
Paul has in mind their pre-conversion existence. Paul is saying that before they converted to Christ, they lived sinful lives, but now they live by the Spirit. We can deduce that in the flesh
refers to the pre-conversion state because Paul uses the same terminology in Galatians 5:24 to refer to the pre-conversion state. There he states that those who belong to Christ have crucified the flesh. Further, Paul clearly sets up a contrast between living in the flesh and living by the Spirit in Romans 7:5–6, where living by the flesh is a past state that is no longer applicable to those who live by the Spirt. Given that being in the flesh
is a past state in contrast with living by the Spirit, being in the flesh
likely refers to a pre-conversion state.
Some contend that when Paul refers to being in the flesh,
he has in mind living a physical existence while succumbing to the weakness of the flesh. These contend that Paul uses the term flesh
in a variety of ways to refer to bodily existence, human weakness, and opposition to God. Thus, Paul likely balances all of these notions when he refers to being in the flesh,
suggesting that being in the flesh is succumbing to the weakness of bodily existence, which leads to sin.
While this interpretation is plausible, it does overlook one important detail, which is that Paul uses the imperfect active indicative form of the verb to be,
which suggests that being in the flesh
is a past state. In particular, Paul writes when we were in the flesh.
The imperfect active indicative refers to an ongoing past state, which means that Paul is referring to when they were in an ongoing state of being in the flesh
in the past. Of course, if being in the flesh
is a past event, this cannot refer to the fact that they are physical and weak, because they are still physical and weak.
Thus, when Paul refers to being in the flesh,
he likely has in mind their pre-conversion state when they lived by the passions of this world.
Interpretation 1:
In the flesh
refers to the unbeliever who is not in Christ.
Summary:
Paul refers to unbelievers as those who live in the flesh. To live in the flesh is to be an unbeliever who simply lives by the passions of the flesh.
Before we came to know Christ, we were led by our passions of the flesh. Now that we belong to Christ, we must resist fleshly passions and be controlled by the Spirit.

Minor differences:
Our authors agree that when Paul refers to being in the flesh,
he has in mind the person before becoming a believer.
For Douglas Moo, the phrase in the flesh
refers to the non-Christian who is enveloped in, and controlled by, the principles and values of this world. Further, Moo characterizes flesh
as a power that is in opposition to the Spirit.1 So to be in the flesh is to be a non-Christian who is controlled by a power that is in opposition to the Spirit.
Frank Thielman has a similar view, suggesting that when Paul refers to being in the flesh
in Romans 7:5, he has in mind the believer who has been sanctified by Christ looking back on his pre-conversion existence.2

Interpretation 2:
In the flesh
refers to a determining condition that makes one susceptible to sin.
Summary:
There is a strong connection between the fact that humans exist in corruptible physical bodies and the fact that we sin. Paul explains that when we live according to the weakness of our physical bodies, we allow the temptations of this world to overcome us.
Advocates:

Leon Morris
Minor differences:
Our authors agree that when Paul refers to being in the flesh,
he has in mind the connection between our physicality and moral behaviour.
Leon Morris explains the view as the notion that physical weakness leads to moral weakness. He points out that while there is a sense in which we can resist being in the flesh,
our physical existence in this life and the weakness of the flesh ensure that we are always open to temptations of many kinds, and to be in the flesh
describes a way of life that succumbs to these temptations.5
James Dunn agrees that when Paul refers to being in the flesh
there is both a physical and moral component that are tightly connected. He also suggests that there is a communal aspect to being in the flesh, related to national badges such as circumcision. So being in the flesh
is related to one’s temptations as a physical being and putting confidence in one’s national identity.6
