Renewal and Sanctification

From David Peterson's Possessed by God: A New Testament Theology of Sanctification and Holiness:

"What makes me a new person in Christ is essentially faith in God and his promises.  The Spirit's ongoing task is to renew my 'mind' through the gospel and give me a new 'heart' to serve God in faith and obedience.  Renewal of mind and heart transforms character and behaviour because of the central place that the mind has in the orientation, attitudes and beliefs of the human personality.  Renewal is not simply at the rational level, though this is foundational to the whole process of moral renewal and change that is effected by the Spirit.  In the final analysis, renewal is the present experience of glorification through the Spirit, anticipating the glorification that will come with the resurrection of our bodies.  It is being conformed to the likeness of Christ, who is himself the image of God." (p.133)

...

The Spirit's regenerative work brings us to faith in Jesus as Saviour and Lord.  This sanctifies us by consecrating us to God in a new and exclusive relationship of heart-obedience.  The Spirit's renewing work continues in us as we trust in what Christ has done for us and seek to reflect in our lives the practical consequences of our union with Christ in his death and resurrection.  Put another way, the Spirit moves us and enables us to express the holiness which is required of those who have been sanctified in Christ." (p.133)
