Abba Father

In this week's passage, Paul describes for us the person who walks according to the spirit in contrast to the one who walks according to the flesh. Is Paul saying here that it is possible for the believer to cease to live according to the Spirit and to thus loose his or her salvation? How do we know? What other passages in the New Testament have a bearing on this question? What is not characteristic of the Spirit that the believer has received? What evidence does the Christian have that he or she is a child of God? How is the idea of addressing God as our Father new? How do we know it is okay to do so? What is the special significance of the phrase "Abba Father?" (52 min)
