The modern distinction between the "carnal Christian" and the "Spirit-filled Christian" is a dangerous one. If a carnal Christian is described as one whose fallen nature has not yet been changed by grace, it is a contradiction in terms. If a person is carnal in the sense that the Holy Spirit resides in him without affecting his constituent nature in any way, then he is simply not a Christian. To view regeneration as not effecting any real change in the person is a serious distortion of regeneration. Here the Holy Spirit indwells but does nothing to effect change in the person.
If a Spirit-filled Christian is defined as one in whom the flesh is absent entirely, then the only Spirit-filled Christians are those now in heaven. Every Christian is to some degree carnal in this world, insofar as the remnants of the flesh are still there provoking warfare. In this sense, the Apostle Paul, after his conversion, was a carnal Christian. Every Christian is also spiritual in that the Holy Spirit indwells him and works in him, through him, and on him.
The biblical view involves the indwelling of a divine person within a human person who has been truly regenerated by the power of the divine person. The human person has changed. His old nature is dying, and by cooperation with the grace of the Holy Spirit, the new man is growing into conformity to Christ.
Thank God for the ministry of the Holy Spirit working in, through, and on you.
