Hebrews 12:18-24 (ESV)
For you have not come to what may be touched, a blazing fire and darkness and gloom and a tempest  and the sound of a trumpet and a voice whose words made the hearers beg that no further messages be spoken to them.  For they could not endure the order that was given, "If even a beast touches the mountain, it shall be stoned."  Indeed, so terrifying was the sight that Moses said, "I tremble with fear."  But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering,  and to the assembly of the firstborn who are enrolled in heaven, and to God, the judge of all, and to the spirits of the righteous made perfect,  and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel.
And to Jesus the mediator of a new Testament, and to the sprinkled blood that speaks a better word than the blood of Abel. Of course Abel’s blood accuses with the law. But Jesus blood forgives. This blood sprinkled, the blood of the perfect sacrifice splattering upon us, our hearts, our consciences, our souls, our flesh, it forgives. It atones. To this we have come, not to the law, but to the gospel. So it is we return Sunday after Sunday, day after day to hear his words. The wonderful gospel that our sins are forgiven.
