As I am still reading some of Donald Bloesch's thoughts in his two volume (now published as one) Essentials of Evangelical Theology, I will provide a quote from him with some reflections. Bloesch states,
"Justification by faith is often considered the antithesis of salvation by works. Yet we should remember that according to the biblical witness faith does not exclude works but gives rise to works. Works of the law as well as of faith are excluded from justification, however, since the ground of our acceptance before God is not our works but Christ's atoning work on the cross. As Warfield puts it: 'Justification by faith does not mean... salvation by believing things instead of doing right. It means pleading the merits of Christ before the throne of grace instead of our own merits.'"
Justification by faith therefore, is far more than a statement we affirm, as if St. Peter is standing at the pearly gates with a scantron test ready to quiz us. Justification by faith entails a grasping of Christ by faith, and not an attempt to grasp salvation, redemption or forgiveness through our own merits. In Matthew 7 we are told of a man who stood before Jesus attempting to weild his spiritual gifts as merits - and Christ would have none of it. "I do not know you," was Christ's judgement upon him. In faith, we do not grasp justification, forgiveness or sanctification, but we grasp Christ, because in his faithfulness he has grasped us. Likewise, sanctification is the benefit of a life that grasps Christ by faith. It is, likewise, not of works, but of faith as well. But faith, through the grace of God, leads to the faithfulness of his people.
