II Corinthians 3:10-11 stresses Christ’s superiority to Moses: by his motivation and permanence. The Mosaic Covenant, based on 10 WORDS, came with unquestioned glory—see Part III. Though a God-appointed temporary expedient and stop-gap measure. Though it brought guilt by detailing the many ways we can sin. Though it had only corrective and judiciary powers.
Christ’s infinitely greater and eternal glory, see Part III, eclipses Moses’ transient glory: as love surpasses law, as expandable surpasses limitation; as delight surpasses terror; as openness surpasses secrecy; as people surpass stone.
Recalling Paul’s words in Romans 7:7-25, the defect wasn’t in Law but in humanity. Nor any defect in Christ’s grace but in humanity’s invariable submission to temptation. What is the difference in Law and Grace, then, since humanity offends both?
MOTIVATION and PERMANENCE! No one can perfectly obey all laws, especially God’s Perfect TEN. James 2:8-13 discusses that. And no one but Jesus ever surpassed ALL that Law demanded and ALL that Grace expected! That is forgiven humanity’s hope. While law and grace convict the sinner, only Grace goes beyond sin to justifying the sinner by faith in Christ’s ALL-SUFFICIENT perfection in both Law and Grace and his sacrifice on Calvary to declare righteous all who trust him and his sacrifice.
