For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit set their minds on the things of the Spirit. To set the mind on the flesh is death, but to set the mind on the Spirit is life and peace. (Rom. 8:5-6).
Most good dictionaries will define bipolar as “a condition of one having or being marked by two diametrically opposed natures or views.” In our Scripture today, we have two forces bidding for the affections of the Christian believer. It is urgent that we understand what the apostle Paul meant by the things of the flesh and life in the Spirit.
It is my understanding that by Paul’s use of the flesh he means our entire human personality under the control of our fallen nature including our mind and spirit as well as our body. I take this from John Wesley, who did not restrict his definition of the flesh to merely bodily or fleshly appetites, but to the corruption of human nature as it spreads through all the powers of the soul as well as to the members of the body.
While the apostle is faithful to warn us against a mindset on the things of the flesh, his real purpose in this classic passage on New Testament spirituality is to show us God’s plan of spiritual power for a new life in Jesus Christ. He called it Life according to the Spirit in contrast to life according to the flesh.
After yielding my heart and life to Jesus Christ in early July, 1946, I had struggled enough with the urges of my fallen nature so that with my mother’s counsel on Paul’s meaning of Life in the Spirit in Romans 8, four months later I went alone into the forest near our home and settled in my heart to know the New Testament experience for the believer promised both by John the Baptist and our Lord Jesus Christ: the baptism with the Holy Spirit and fire (Matt. 3:11: Acts 1:5,8).
