When a man is unsaved (without faith in the cross)–he hates God’s law, and only loves the pleasures of the flesh.
When a man is saved (with faith in the cross)–he sees clearly that he is wicked, and deserving of Hell. Formerly, he hated righteousness, but now understands that “without holiness no one will see the Lord” (Hebrews 12:14). So, although he understands he cannot live perfectly righteous, he still tries to keep God’s commandments out of a fear of Hell, and of the fierce wrath of God on Judgment Day. As he tries to live a righteous Christian life, he experiences an evil resistance coming from within himself (Romans 7:14-25). And the voice of God may whisper to him, “That’s why I died on the cross.” And he sees that, although God delights in the Christian’s desire to keep His commandments from the heart: still, “all our righteous acts are like filthy rags” (Isaiah 64:6), in the sight of a perfectly righteous God. So, the Christian, while trying to live righteously throughout his life–resisting temptations of all kinds–acknowledges that without the ability to look to Jesus dying on the cross for his sins, and the practice of regularly repenting, and keeping a clean conscience with God, by accepting His forgiveness of sins–that (somewhat) righteous Christian would still burn in Hell forever! He knows that without the help of Jesus, he would be a goner!
