The last four chapters constitute a very practical and concrete application of the doctrinal, an infusion of the effects of the truth into the life. Paul pleads for holiness. We take nothing away from that. But consider this. Real grace is so much more than this.
Real grace calls people to real holiness.
It calls people to rise above the bankrupt possibilities able to be generated apart from God and to come closer to Jesus than ever before. That is, live it out, put it to the test, test the mettle of what God is willing to do through you. It's not our will we are proving, but God's will. Under the Holy Spirit's power Paul presents three ideas about the experience we ought to be living. That is, as Christians so many are living beneath their privileges.
