who in time past were no people, but now are God's people, who had not obtained mercy, but now have obtained mercy.
 In the case of the Christian all is changed. For Christ communicated a new nature which loves to obey God's will, which accordingly is given us from conversion, before (and it may be long before) a person enjoys peace. From the time that this new nature is given, the purpose of the heart is to obey. Such was, unhindered by imperfection, the obedience of Jesus.
