“Christ drives us back into the inner chambers of our consciousness, where God and we are alone, and good an evil assume a proportion and significance never dreamt of before. The law in the hands of Jesus becomes alive with God’s own personality. Majestic and authoritative, he is present in every commandment, so absolute in his demands, so observant of our conduct, so intent upon the outcome, that the thought of giving him less than heart and soul and mind and strength in the product of our moral life ceases to be tolerable to ourselves.” – from a collection of sermons by Vos titled Grace and Glory. Sermon title: Hungering and Thirsting After Righteousness – Matthew 5:6
This is exactly it. The Law finds a continued use for the believer because it drives us to Christ, ALWAYS!. We find our moral life intolerable and beg the Saviour, not only save us from hell, but save us from our sins.
