Hebrews 10:28-31

Anyone who disobeyed Moses’ law died without mercy on the simple evidence of two or three witnesses. How much more severely do you suppose a person deserves to be judged who has contempt for God’s Son, and who scorns the blood of the new covenant that made him holy, and has outraged the Spirit of grace? For we know him who said, “I have the right to take revenge and pay them back for their evil!” And also, “The Lord God will judge his own people!” It is the most terrifying thing of all to come under the judgment of the Living God!
