My friends, if anyone is detected in a transgression, you who have received the Spirit should restore such a one in a spirit of gentleness. Take care that you yourselves are not tempted. Bear one another’s burdens, and in this way you will fulfil the law of Christ. For if those who are nothing think they are something, they deceive themselves. All must test their own work; then that work, rather than their neighbour’s work, will become a cause for pride. For all must carry their own loads. (Galatians 6: 1-5)

Paul does not so much place flesh and Spirit in contention as he contrasts the work of the flesh with the work of the Spirit.

If our object is to satisfy the flesh - a narrow and lonely aspect of the self - our work will produce nothing of value.

But if our effort is guided by the Spirit - the self in relationship with others and with God - we can co-create profound value.
