This self-giving of God and of Christ take form in the lives of believers and saints, especially those who are persecuted for the sake of the Gospel and martyred. On that account St. Paul sets himself and his companions in their sufferings as patterns of sanctification for those to whom they preached the Gospel. As magnificently monergistic as our sanctification is, that is, God works in us to create and confirm faith and to do good to others, we Christians are plagued by sin. In actual practice our sanctification is only a weak reflection of Christ's life. Good motives often turn into evil desires.
Good works come to be valued as our own ethical accomplishments.
The sanctified life constantly needs to be fully and only informed by Christ's life and death or our personal holiness will soon deteriorate into a degenerate legalism and barren moralism. God allows us Christians to be plagued by sin and a sense of moral inadequacy to force us to see the impossibility of a self-generated holiness. Our only hope is to look to Christ in whom alone we have a perfect and complete sanctification.
