See that ye refuse not Him that speaketh. For if they escaped not who refused Him that spake on earth, much more shall not we escape, if we turn away from Him that speaketh from heaven… – Hebrews 12:25

The Lord has made a law which is perfect, and just, and good. Would you rather be without law? What reasonable person desires anarchy? God has backed up that law with a threat. What is the use of a law if to break it involves no consequences? A government that never punishes offenders is no government at all. God, therefore, as moral ruler, must be just, and must display His indignation against wrong and evil of every kind. It is written on the conscience of men that sin must be punished. Would you have it go unpunished? If you are a just man, you would not. To meet the case, therefore, the Lord Jesus Christ, by Himself bearing the penalty of death, has honored the divine law. He has shown to all intelligences that God will not wink at sin that even His infinite mercy must not come in the way of His justice. This is the doctrine; do not listen to those who twist and pervert it. It is the love of God which has provided the great atonement by which, in a judgment better than ours, the law finds a glorious vindication, and the foundation of moral government is strengthened. Do consider this matter, and judge it fairly, with candid minds. We assure you from God’s Word that apart from the atonement of our Lord Jesus you can never be saved either from the guilt or power of evil. You will find no peace for your conscience that is worth having, no thorough and deep peace, except by believing in this atoning sacrifice, neither will you meet with a motive strong enough to rescue you from the bonds of iniquity. Therefore, “See that you refuse not Him that speaks.” Hear, and your soul shall live. Quibble and you will die in your sins. ~ C.H. Spurgeon
